There you are, sitting in the food court at the mall. You’re minding your own business, eating an ice cream cone with your friends. Suddenly, music begins to play and people begin to appear out of nowhere and start to dance. What’s going on? It’s a flash mob!

A flash mob is defined by Webster’s New Millennium Dictionary of English as “a group of people who organize on the Internet and then quickly assemble in a public place, do something bizarre, and disperse.” Flash mobs got their start on June 3, 2003.

On that day, more than 130 people showed up in the ninth floor rug department of Macy’s department store in New York City. When asked what they were doing, the people told salespeople they were shopping for a rug as a group!

The idea for the flash mob came from Bill Wasik, the senior editor of Harper’s Magazine. Why did he start these crazy gatherings? Because he could! Flash mobs were invented as a fun social experiment meant to encourage spontaneity and large groups of people to take over public areas temporarily just to show it could be done.

Flash mobs quickly became popular, particularly amongst young people. Videos of flash mobs went viral on YouTube. Other social media outlets, such as Facebook and Twitter, allowed flash mobs to be organized between friends and acquaintances and then shared with non-participants after the event occurred.

The essence of a flash mob is a large group of people suddenly assembling in a public place to perform an unusual act for a brief period of time before dispersing quickly as if nothing had happened. Some flash mobs are meant to entertain, while others are purely for artistic expression. Still other flash mobs are purely for the enjoyment of the participants, as they watch the reactions of those around them.

Today, flash mobs are still popular in many cities around the world. College campuses are also often popular spots for flash mobs. Although they’re not as popular as they once were, flash mobs will continue to live on as long as there are large groups of people willing to take part in short, random acts of pure silliness!

  1. We have never heard of flash mobs but we think it is cool that all those people came together to dance in the mall. We think it would be fun to do that as a class.

    We think tomorrow’s wonder will be about fathers, aunts, grandmothers, cousins, or family members other than uncles! We also think it could be about ants!

    • Hey there, Wonder Friend Ms. Bayko’s Class! We love your enthusiasm for today’s Wonder– we hope you will flash mob as a class soon! We bet you’d do a fantastic job!

      Thanks for telling us all about your awesome predictions for the next Wonder of the Day®… we think you’ll be marching along with us tomorrow! :)

  2. Thoughts: How do flash mobs choose the songs they use? (Brandon) Do flash mobs practice before they perform in public? (Leslie) How did the group of people plan the flash mob? (Michelle)

    Connections: This reminds me of when I got a group of friends together and we were dancing because the flash mob got together and danced. (Kevin) This reminds me of the movie Step Up 4 or Revolution because there is a flash mob at the beginning of the movie. (Pedro)

    Predictions: What is a family tree? (Briahna) Who were our forefathers? (Jake) Are you an ant? (Jaaron) Do you have a favorite aunt? (Shalize)

    Sorry we didn’t write yesterday, we were a little too busy! Mrs. Hess gets to tell other teachers about Wonderopolis tonight at her meeting! We’re curious how you will celebrate the thousandth wonder question.

    • HOORAY, we’re so glad our Wonder Friends in Mrs. Hess’ class learned about a cool social experiment today! Flash mobs are lots of fun, whether you’re watching or participating! We think any upbeat and energetic song is great for a flash mob, but it depends on the setting! Flash mobs involve a LOT of practice– sometimes it happens in another space (like a dance studio), or other times it happens VERY early in the morning, before people are out and about!

      We are glad you shared your thoughts, connections and predictions with us today! Brandon, Leslie, Michelle, Kevin, Pedro, Briahna, Jake, Jaaron, and Shalize did a SUPER job of WONDERing today! We hope your meeting tonight goes great, Mrs. Hess! Thank you for sharing the Wonder with all the awesome teachers at your school! :)

  3. Thoughts, questions, connections: Cassie- That video was crazy! Savion- Did you know that Beechgrove was the first entire school to have a flash mob? Ashleigh- I think it would be cool to have a flash mob on our school trip to Chicago! Sierra- At my church, our youth group we did a Harlem Shake flash mob. Chaney- The dancers in the video were terrible. Samantha- How many flash mobs are there in a year?

    Predictions: Christian- What do ants eat? Erica- How many different types of ants are there? Savion- How many ants can live in an anthill? Mia- How strong is an ant? Stephanie- Is an aunt an ant? Cassie- Do ants travel over the world? Samantha- How much food do ants eat? Josh- What kind of relative is an aunt?

    • We learned so much from your WONDERful comments today, Mrs. VanDusen’s Class! We think it’s awesome that some of you have participated in a flash mob already! HOORAY to Cassie, Savion, Ashleigh, Sierra, Chaney and Samantha for sharing your thoughts, questions and connections!

      We love your guesses for tomorrow’s Wonder, Christian, Erica, Savion, Stephanie, Cassie, Samantha and Josh! We can’t wait to march along with you tomorrow… :)

  4. Wow….Ha That Was Hilarious!!! :D
    It Would Be weird If A Bunch Of older people Did That…That Would Be weird!!!
    Is tomorrow’s Wonder Aunts Or Ants?!!! :D

    • We Wonder if you have ever seen a flash mob in person, Wonder Friend Max? We bet it would be lots of fun to watch, or even to participate! We look forward to WONDERing with you tomorrow… we think you’re on the right page! :)

  5. We liked this a lot and we really want to do one too. Austin says he wants to break dance. : ) Scott wants to see one at his mall and Makenzie wants to do one this weekend herself and her song is going to be Scream and Shout (the clean version though).

    Makenzie, Scott and Austin

    • Good afternoon, Wonder Friends Makenzie, Scott and Austin! Thanks for visiting us today as we dance around Wonderopolis! It sounds like there’s a lot of rhythm in Mrs. Nolan’s 5th grade class! We hope you will all dance your hearts out, whether it’s through break dancing, watching a flash mob, or even participating in one! WOOHOO for WONDERing! :)

    • Hey there, Wonder Friends Grace W and Simranjit D! It is great to hear that you enjoyed our flash mob Wonder– what a fun day! We found today’s Wonder video on vimeo, another site full of videos! We Wonder if either of you have participated in or have seen a flash mob? :)

  6. What is up Wonderopolis,
    It’s me Mushakale! Remember how you guys had a wonder that was about dancing? I think it was sort of like a flash mob. Anyway back to the topic I thought that this wonder would be sort of like the harlem shake. But I was wrong and you were right! Have you noticed that I am the 4th person to comment? Come on people comment! I have to go bye.
    From: Mushkale :) ;) :p :D

    • Welcome back, Mushkale! We are so happy you’re visiting us today! We LOVE all the connections you made to other popular dances, like the Harlem Shake! That dance has gone viral, which is the topic of this Wonder: #754– What Does it Mean to go Viral? :)

      We are always so excited when you come back to visit us and share your awesome comment! We hope to see you again, Wonder Friend! :)

  7. We had a Make a Wish volleyball tournament and after one of the games the music started and we had a flash mob. I was in it and it was really cool and fun.
    First we danced to “Scream and Shout” then we danced to “Gangnam Style”. It took a whole month and a half to prefect it for the M.A.W tournament but it was AWESOME.

    • WOW, what an amazing story, Opinion_Girl.13! Thank you very much for sharing your flash mob experience! We bet it was a lot of fun to prepare for the final dance, and it’s even cooler that it supported a great cause!! We’re dancing around at Wonderopolis thanks to your inspiring comment! :)

  8. Thoughts: (Emilee) I thought the video was very funny when all of these girls started it, then one boy joined in at the end. (Brian) I thought it was funny to see someone dancing with a lot of other people. [Taylor) I thought it was fun because the dancers were having a good time.

    Connections: (Luke) When I was 8 I went to Virginia Beach and there was a big flash mob. (Keyara) I did a flash mob in Miami at the mall when I was 7. (William) When I was at Greenwood Mall there was a group of people doing a flash mob for Breast Cancer.

    Predictions: (Meghan) Who Is Your Aunt? (Shelby) Who Came Up With the Names Aunts and Uncles? (Breon) How Are Aunts a part of your Family? (Ben) How Did Father’s Day Start? (Shaviyana)How Can You Become an Aunt?

    • Good morning, Mrs. Coleman’s Class! We are so happy you were dancing in your seats as you WONDERed about flash mobs with us! HOORAY!

      Emilee, Brian and, Taylor shared some awesome thoughts that made us smile! We like your enthusiasm! :)

      Luke, Keyara, and William have their very own connections to share– it looks like all of you have participated in or have seen a live flash mob! Such a cool experience! :)

      Meghan, Shelby, Breon, Ben, and Shaviyana, you’re on the right track! We bet you’ll be surprised by the next Wonder of the Day®! :)

      See you soon, Wonder Friends! :)

  9. It’s Tony again but today’s wonder is pretty easy for me to answer and I was in a flash mob and it was for Make-A-Wish fundraiser to kick off a special event to raise money to grant a kid’ (that has cancer) wish but there is a kid in my school who has cancer and is in 7th grade and his wish is to go to Australia for the summer and I wanted to grant his wish.

    • Welcome back to Wonderopolis, Tony! We are thrilled to hear about your awesome flash mob experience– it sounds like you and another Wonder Friend (Opinion_Girl.13) have both participated in a flash mob to support Make-A-Wish Foundation! What great Wonder Friends we have! Thank you for visiting and telling us all about your cool flash mob! :)

  10. Loved the flash mob links!! They look so fun & we would love to be part of one some day. We think tomorrow’s wonder is about aunts or ants! Can’t wait!

    • HOORAY, we are so glad that you enjoyed our variety of flash mobs! We had a grand time watching all the different ones, too! We’re dancing here at Wonderopolis! We hope you’ll join one in the future– it looks like a great time! Thank you for sharing your guesses for tomorrow, too, Gwen and Angus! We think you’re on the right track! :)

    • Hey there, Wonder Friends Rat and Yojo! We LOVE that you are both predicting tomorrow’s Wonder of the Day®! We think you’re doing a great job of sharing your ideas… and we bet you’ll be surprised by tomorrow’s Wonder! :)

  11. Hey I like what I was reading. It was a really good passage. That is good to know. Can you only have it at a mall? Can you have it at school or something?

    • Hey there, Wonder Friend D’Anya! Thanks for visiting Wonderopolis to Wonder about flash mobs– they can take place nearly everywhere! We’re so happy you’re thinking outside the box with the help of today’s Wonder topic… we bet you’ll enjoy the flash mob video links from today’s “Try It Out” section! Check it out! :)

  12. I think flash mob is a freedom speech because they maybe think that dancing is a freedom. I think also that they want people to get up and dance and loosen their body. Sometimes it’s just to entertain and cheer them up if they’re feeling down.

    • What a great point, Beast_Guy! It’s great that you’ve been thinking about the connections between dancing and freedom of speech! Good for you! Also, we think it’s great that you mentioned how dancing makes you feel– sometimes it can bring a smile to someone’s face when their day is not so great! It’s a SUPER way to exercise, too! So many great things go with dancing! Thanks for sharing your comment today! :)

  13. Hi Wonderopolis! I loved today’s wonder! I did not know anything about flash mobs until I read your article! I thought the video was cool too!

    I think tomorrow’s wonder will be about family members other than uncles!

    • WOOHOO, we’re so happy to hear that you learned something new with us today, Wonder Friend Holly! Flash mobs make us smile, especially when we can join the fun! We hope today’s Wonder made you smile and we look forward to WONDERing with you again soon! Great prediction for tomorrow’s Wonder! :)

  14. I think flash mobs are cool because at some random time music is going to suddenly come on and people are going to suddenly start dancing. I think it can be a negative thing to do because if you are going to do it in school, you might want to ask permission first so you don’t get in trouble.

    • We are so excited to read your comment today, Wonder Friend Aubree! You did a great job of pointing out the positives and negatives of a flash mob! WAY TO GO! You made a great pro/con list! We think you bring up two WONDERful points– we wouldn’t want anyone to get in trouble for dancing! If you would like to plan a flash mob, it’s important to check that you’re not disrupting anything, especially at school! :)

  15. I think that flash mobs should always be allowed because it is a way to have fun and loosen up and be silly. I think people should get in trouble because of them because they are just for fun.

    • We love all your reasons for supporting flash mobs, Wonder Friend Michael! NICE WORK! It sounds like some other Wonder Friends agree with you about the great reasons for having a flash mob! Like Wonder Friend Aubrey mentioned, it’s important to ask for permission before performing a flash mob of any kind. We wouldn’t want to disrupt anything or be disrespectful, so making sure it’s okay is a great idea! After all, it’s all for fun! :)

  16. Hey Wonderopolis! I’m Not Really Sure What a Flash Mob Is Til I Watched The Video And Took A Look At The “Did You Know” And I Found Out! At First I Thought It Was A Group of People Coming To a mall and start dancing for a weird reason! I Found out I was right but I forgot the music turns on part! And like always Me and my brother did this with each other! Love You Always!

    From: Landon Kushneryk and Lukas Kushneryk

    • WOW, we’re so happy to hear that our Wonder Friends Landon and Lukas have performed a flash mob on their own! NICE WORK! It sounds like you learned something new about a cool social dancing experiment– and you tried it out yourselves! Thanks for telling us all about it– we’re so happy you visited Wonderopolis today! See you soon, Wonder Friends! :)

  17. I think a flash mob is super duper cool. I would love to do a flash mob and it looks super fun. I think a flash mob is a good thing because kids can get good exercise and just have a great time. Just maybe some kids might not have gym class every day.

  18. Flash mobs are where people go and dance in front of a crowd and people just join in on the dance. I am from Minnesota, USA. There was an incident with this guy who suspended these kids for doing a flash mob that they got permission to do the event.
    I think that a flash mob is ok as long as they have permission to do it. Then GO FOR IT!

    • Hey there, Wonder Friends Sami and Kelsey! Thank you for sharing your awesome comments about our flash mob Wonder! HOORAY for dancing! :)

      Sami, you make a great point about having fun and dancing to exercise! How true!

      Kelsey, we absolutely agree with you about asking for permission to perform with a flash mob! It’s important to check first!

      Thank you for WONDERing with us today! :)

  19. There was a flash mob in Minnesota, where I live, it was at a school, at the kids lunch hour. I think flash mobs are okay because they are a way for students like me to express ourselves. Kids can do popular dance or old ones, and we can do funny dances they don’t have to be serious. I don’t think flash mobs are bad but I wouldn’t do it until I had approval and it was organized.

    • Hello, Wonder Friends McKenna and Brooke! It sounds like you both enjoyed today’s Wonder about flash mobs! We’re dancing with happiness here at Wonderopolis! It’s important to remember to get approval first, like McKenna mentioned, when organizing any type of event (even a flash mob)! Brooke, we hope you can join the fun flash mob experience one day- we bet you’d be great! Thanks for sharing your comments! :)

  20. To me a flash mob is a way to show who you are, and a way to be free, and a way to have fun. Today my teacher told us that some kids got in trouble for doing a flash mob when they already had permission. That doesn’t sound right. I think a flash mob would be fun to do. Maybe I’ll do a flash mob one day.

    • Flash mobs are so much fun– and they are a surprise, too! Thank you for sharing your WONDERful comments with us, Amme and Alex! It’s important to ask permission before organizing any event, such as a flash mob, just in case there are restrictions or safety concerns. :)

      We think it’s great that you have been WONDERing about cool events and different ways to have fun! Keep up the great work! :)

  21. I think flash mobs are really cool and i would love to try one with my friends. I think it is fine for kids to do flash mobs because kids just want to have fun and be kids.

    • WOHOO, flash mobs are definitely cool according to Justin and Laura– we couldn’t agree more! WOHOO! Thank you for sharing your comments with us- we hope you can participate in one soon! Keep up the great work! :)

  22. I think it would be cool to do a flash mob because it’s very entertaining to see one and you get to see people dance.

    • There are people everywhere, that’s for sure, Zachary! We like that you’re thinking of all dancing that is involved in a flash mob, Mason! We’re so happy both of our Wonder Friends shared their comments with us today! What a cool way to learn about a crazy, organized social experiment! :)

  23. Hi! My name is Tianna. You might know Brooke because I’m in her class! It’s true my taecher and my class and me, love your website. We can share too. Enough about that! I didn’t know a flash mob was a dance that’s soo cool because I love to dance. I’ve got to say every time I come on your website I keep learning and learning. That’s one reason I love your website. Well I got to go, but my whole class loves your website it’s the best!! I’ll talk to you next WONDER Wednesday! P.S. Brooke will leave a comment trust me. :) :() bye!

  24. I think that flash mobs are cool. I would want to be part of one someday. I like them because they happen out of nowhere.

    • Hello to our awesome Wonder Friends, Maddy and Tianna! Thank you both for telling us all about your favorite part of today’s Wonder! Perhaps you will be a part of one someday! That would be so very WONDERFUL! Please let us know when it happens! :)

      Thank you for visiting us and sharing your SUPER comments- you ROCK! :)

  25. Do people get crash by flash mobs? How do they do the signal and to start? At school there are some people going to do a flash mob. Thanks for information.

  26. Flash mobs are cool I like how peple join in.
    When our teacher showed us the video kids at school started doing a flash mob at school but with Gangnam Style! :) :) :)

    • Hello to our Wonder Friends Alvara and Neon D #15! We love all the cool connections you have each made to our flash mob Wonder! Flash mobs are usually timed, so one person might be in charge of a signal that all the dancers know about. Sometimes it’s the music, sometimes it’s a hand signal. It sounds like you both have seen kids from a school performing in a flash mob! Thanks for telling us all about it! :)

  27. I’m from Minnesota, if you watch the news you would have seen tons of kids doing a dance called the Harlem shake at South High in Minneapolis. It was like a big flash mob. I think it was unfair they got suspended for doing it.

    • Hey there, Wonder Friends Kiki and Macy! We love both of your comments about flash mobs! Kiki, we bet your performance was out-of-this-world awesome! :)

      Macy, thank you so much for telling us all about the students who performed in a flash mob. This is a great reminder to all of us that we should ask for permission if we plan to organize an event, even a flash mob! We appreciate your comment and we are so happy you visited us! :)

  28. I think that flash mobs are pretty cool. When do they often happen though? Well because my teacher talked about a flash mob at school and they got in trouble when they had permission (like the people said in the other comments). That to me is just wrong. The kids had permission and it looked like they were having fun. I really want to be in one sometime! They sound like they would be awesome to be a part of.

    • Good afternoon, Wonder Friends Chloe and Paula! Flash mobs are making you smile, and we are smiling, too! Thanks for telling us what you’ve been thinking about flash mobs after enjoying our Wonder! We hope you are dancing in your seats after learning all about flash mobs! :)

  29. That this can be fun but this is a health thing to do because it gets your heart racing and everone get their heart racing not just you.

  30. I think it would be fun to do a flash mob and I think you should not get in trouble just because you want to dance with your friend like the kids that made the harlem shake.

    • Thank you for sharing your comment, Wonder Friend Andrew! It sounds like you’d be up for a flash mob in the future! We bet it would be a great time, as long as you ask permission first! :)

    • Hi Wonder Friend Austin! We’re always looking for new things to Wonder about– some of our Wonder Friends have been a part of a flash mob! We Wonder if you have seen one in person? Sometimes you just want to dance and have fun! :)

  31. The Harlem shake is just a flash mob but it starts with one person then people join there is nothing wrong with that.

    • The Harlem Shake has become another phenomenon recently, hasn’t it, Alejandro?! We think you made a great connection to our flash mob Wonder– a few people start it and then others join! Thanks for sharing your comment with us this morning! :)

    • WOW, that’s awesome, McKenzie! It sounds like a very fun way to dance, especially with your friend! We Wonder if you have a favorite song to dance to? :)

    • We are glad to hear it, Wonder Friend Gabrielle! :) We couldn’t resist the pun! :) We Wonder if it’s stuck in your head? :)

  33. I’m in a flashmob at my school, OLHMS. It’s super fun. We did a make a wish vollyball game we danced to scream and shout and gangnam style! It was super fun and I’m going to to it at a school talent show.

    • WOW, how cool, Alexis! It sounds like you’ve got a super cool connection to our Wonder about flash mobs! Good luck at your talent show– we think you’ll do a WONDERful job! :)

    • Thanks for telling us, Wonder Friend Gabe! The Harlem Shake has been a very popular flash mob song lately, hasn’t it? What a great connection to our Wonder! :)

  34. I have been in a lot of flash mobs! I have danced to Don’t Stop The Party, Just Dance, Gangnam Style, Call Me Maybe and even more!! It’s so fun and amazing! My favorite part of it is the look on peoples faces when we start! It’s hilarious. The team of Wonderopolis should do a flash mob! Then post it on the websites. That would be awesome. I would totally watch it. Just a hint…please do it.

    • WOW, it sounds like you’re a flash mob champion, Muggy! We’re so glad you have a cool connection to our flash mob Wonder, and we like your comment about everyone’s reaction to a flash mob!

      Thanks for your awesome suggestion about a Wonderopolis-inspired flash mob, too! You’re so creative! :)

    • We love your enthusiasm, Miss Rivas! We hope you’ll participate in a flash mob in the future, too! Perhaps you will even help to choreograph the dance! We Wonder what song you’d like to dance to in the flash mob? :)

  35. I would love to be a part of a flash mob. It seems really really fun. I would love to see the people’s reactions.

    • We think it would be a very fun experience, too, Wonder Friend Jean! Thanks for sharing your comment! We hope you dance your heart out in a flash mob soon! :)

  36. I thought that video was so crazy. I would never do that in public. It would be embarrasing for my family and me!

  37. I love this because there is a flash mob on the computer and we listened to it in my classroom, and my friend was in it J and K, they were doing a soccer thing and then they switched to dancing.

    • How awesome that you’ve been WONDERing in your classroom, too, Jozi! It sounds like some of your Wonder classmates have already been a part of a flash mob– how neat! :)

Ask a friend or family member to join you as you explore one or more of the following activities to extend your learning about flash mobs!

  • What is it about flash mobs that appeal to people? Give it some thought. Is it the surprise aspect? Or being involved in something as a group? Is it performing in public? Or just the silliness of it? Talk about flash mobs with your friends and family members. Explain to them what they are and how they get started. What do they think? Would they want to be a part of a flash mob? How about you? Why or why not?
  • Never seen a flash mob? Check out these cool videos to see some flash mobs in action:
  • Up for a challenge? Organize your own flash mob! That’s right! You can organize your very own flash mob in your neighborhood or even on the playground. Here are a few things to keep in mind as you plan your flash mob:
    • Be entertaining! Flash mobs are about performance, so make sure you plan to do something that will be fun for friends and family members to watch. For example, an impromptu dance routine on the playground would make for a fun flash mob!
    • Get organized! Contact your friends to get them to help you plan and participate in your flash mob. Be sure that everyone understands what you’re doing, when you’re doing it and why you’re doing it.
    • Don’t be disruptive! If you’re planning a flash mob at recess at school, make sure to get permission from your teacher and/or principal. Who knows? They may even help you plan or participate!
    • Have fun! The most important thing about a flash mob is that you have fun. As soon as you’re finished, make sure everyone involved acts normal and blends back into the crowd. Acting like nothing ever happened afterward is part of the fun of a flash mob!
    • Record it! If at all possible, have someone videotape your flash mob. When you’re finished, upload your video to Facebook to share with all your Wonder Friends. We can’t wait to see your flash mob!

Still Wondering

Using National Geographic Education’s Crowded Places activity, children describe crowded and uncrowded places, brainstorm possible reasons for crowding and brainstorm good and bad things about living in a crowded place.
