How fast does sound travel? Can you create your own sonic boom? Wonder What's Next? Try It Out Are you ready to fly? Find a friend or family member to help you explore the following activities: Do you need an airplane to make a sonic boom? Not necessarily! Head online to watch a video of Chris Giorni from Tree Frog Treks making a " sonic boom " using a few common household items.
You might also be able to make your own sonic boom in your yard if you've been to the rodeo recently. Do you have a bullwhip? Bullwhips are common on farms, and they also make great souvenirs at the rodeo. If you've ever used a bullwhip, you're probably familiar with the loud cracking sound it makes.
That sound is actually a tiny sonic boom. When a whip is swung, energy travels from your hand through the whip to its end. By the time all that energy travels to the end of the whip, its tip — called the "cracker" — is traveling faster than the speed of sound.
Like a supersonic airplane, the end of the whip surpasses the speed of sound and the bunched-up sound waves make the cracking sound you hear! Scientists believe the bullwhip may have been the first human invention ever to break the sound barrier.
So, if you have a bullwhip at home, give it a crack. You probably never knew you could create a sonic boom in your own yard! What would it be like to fly faster than the speed of sound? Put your imagination to the test. Envision yourself in the cockpit of a fighter jet. You push the throttle to its limit and you rocket into the sky.
What do you see? What do you hear? Write a short story about your imaginary trip to Mach 1 and beyond. Share your story with a friend or family member. Would they like to fly faster than the speed of sound? Why or why not? Did you get it? Test your knowledge. What are you wondering?

Join the Discussion. Jan 26, I did a class project on sonic boom and i really liked it. Dec 16, That's great, caleb! Did we forget any information? Colton Nov 18, Nov 18, Thanks, Colton. Emma Mar 8, Hi Colton. Mar 8, That's a plane Luigi, you didn't make it. Aedybug07 Oct 16, I have a question what is another word for the sonic boom when my mom talks about it I think of Sonic the fast food place and a bacon cheeseburger.
Oct 25, Jacob Oct 9, I learned a lot from it and really enjoyed reading it. Next time I go to an airshow, I'll try to catch one.
My favorite planes are the Blue Angels. What are yours? Thanks a lot! Sunder Jun 17, Nice scientific explanation, but why not in the metric system? Jul 2, Apr 23, Caden Apr 24, I have seen a plane called a Blue Angel and it had a loud sonic boom.
Keaton Sep 18, I've seen a lot of Blue Angels. They practice in Pensacola and I visit there a lot. Sep 30, That's a really cool connection to this Wonder, Keaton!
Thanks for sharing! Hi Aug 23, Aug 27, Apr 24, Natalie Aug 29, Aug 31, Karter Dec 2, I've seen this happen at an air show. Cade Sep 27, I really want to see a sonic boom in person. Dec 2, Oh wow, Karter! Did you have to cover your ears? Natalie May 31, May 31, And i wonder if in the future we beat light. May 22, Planes are super cool, alex! Who knows what the future holds! May 9, Ishaan Shetty Feb 14, How does an engine break the sound barrier at almost above mph.
Feb 16, Feb 9, Hi, tracy! Wonderopolis Oct 4, Buckley May 31, Wonderopolis May 31, Madison Apr 19, That's so cool! I like how you could actually hear the boom! When was this video taken? Wonderopolis Apr 20, Wonderopolis Apr 19, We're so glad you thought this Wonder was cool, m0nk3y!
Thanks for letting us know! Robert Apr 16, This video was super duper awesome. I can keep watching this over and over again.
Wonderopolis Apr 16, Two new vocabulary word I learned in this article were bullwhip and sonic boom. A bull whip is something that can break the sound barrier. It is exactly like on of those jets that can break the barrier of sound.
A sonic boom is when something breaks the barrier of sound. It makes an enormous sound,that happens when something breaks the sound barrier. Such as a bullwhip. Two new facts I learned is that I never actually new that something could break the barrier of the sound. I thought that it was impossible to stay alive after breaking the barrier of sound because I heard that a jet was on the mission to break the barrier of sound and the jet exploded.
I wonder if there was ever any kind of alarm clock or something other than that, which produces sound, that can break the barrier. Because I want to get one of those. I also want to get a bullwhip. I'm very exited to write more. BYE :. Wonderopolis Apr 5, I like wonderopolis. It is really good to learn. Wonderopolis Mar 27, Matthew MC Mar 25, This wonder was my favorite yet.
I did not know that however high you are that the speed varies to generate a sonic boom. Like at sea level you have to be going miles per hour to generate a sonic boom. But at 20, ft you can generate a sonic boom at the speed of miles per hour. I did not know that the pilot of the airplane can not hear the sonic boom. I thought that the sound would be much louder. Do you know how loud the loudest sonic boom was and was it made by an airplane? Wonderopolis Mar 26, Srikar MC Mar 23, Hi, this is Srikar from Mrs.
Caplins class. It was really cool when that guy made a sonic boom with soapy water. I learned that sonic boom is a loud sound caused by shock waves created by any object that travels through the air faster than the speed of sound. I had to use context clues when I read the word altitude and I learned that altitude means how high something is.
When was the first sonic boom made? Wonderopolis Mar 23, I see what a sonic boom is. Wonderopolis Mar 22, Clayton Mar 22, I would have to disagree on some of these theories, a sonic boom happens whenever something is going so fast that it breaks the sound barrier causing the sound to be delayed, when that happens you get all of the sound at once causing a loud boom. Food Allergy Girl Mar 21, I think tomorrows wonder will be about airplanes. I am in the hospital again for an anyphylaxis reaction and I am very bored sitting around.
Got to go! I am getting wheeled to the operating room. My real name is Emma! Emma Mar 21, I never really knew what sonic boom meant until now.
I think you guys should do a wonder on titanoboa snakes!!! I know every single person who goes on wonderopolis will read this! TJ Mar 21, Remember on wonder of the day number Have you ever lost your marbles? I commented on it and said that it was the very last comment I would put on Wonderopolis. I meant to say that I wouldn't be commenting on Wonderopolis for a long time. Madalynn Mar 21, Oh I tried the wonder of the day about broadway and the video didn't show up but I did read about it it was really neat!
I loved it! Thanks :. Wonderopolis Mar 21, Bertz's class Mar 21, We really liked today's wonder! We learned all about sonic booms.
We think tomorrow's wonder might be about birds or jets. Tessa Mar 21, That is a quite interesting wonder for today! Do you think you could do a wonder about monkeys?
They are my favorite animal! I really love wonderopolis! It is awesome!!!!! KF Dragons Mar 21, Sonic boom is an impulsive noise similar to thunder.
It is caused by an object moving faster than sound, about miles per hour at sea level. An aircraft traveling through the atmosphere continuously produces air-pressure waves similar to the water waves caused by a ship's bow. When the aircraft exceeds the speed of sound, these pressure waves combine and form shock waves which travel forward from the generation or "release" point.
Wilbanks Mar 21, Very amazing. I love wonderopolis, I think it teaches the children a very good lesson. It is when a jet speeds up and it makes a big boom. Mobile Newsletter banner close.

A sonic boom occurs when an object moves faster than the speed of sound. As it moves through the air, it creates shock waves that can cause a loud, booming sound. It is mostly emitted by aircraft that travel at supersonic speeds. Why is a sonic boom so loud? Numerous pressure waves combine together to form a single shock wave. They have the ability to move faster than the speed of sound. The constant expansion and contraction of air can cause a shock wave that sounds like a loud clap to human ears.
This is why a sonic boom can be so loud. Can a sonic boom hurt you? A sonic boom can severely damage your hearing if you are close enough to the source.
Is making a sonic boom illegal?
