A sonic boom isn't the same as a bomb although sometimes the loud sound you hear when a sonic boom happens sounds that way. It has to do with sound waves and sound energy.

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.

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. Sign up for our email newsletter. Already a subscriber? Sign in. Thanks for reading Scientific American.

After more than a decade of research, NASA successfully captured supersonic shock waves for the first time this year.

Why was breaking the sound barrier such a huge achievement? Breaking the sound barrier proved that the human body could move without injury at the speed of sound, taking us closer to the possibility of space flight. A great example is thunder, which is the sound caused by lightning.

Both occur at exactly the same time, but you see a lightning flash before you hear its thunder because light travels much faster than the speed of sound. It takes the sound of thunder roughly 5 seconds to travel a mile or 3 seconds to travel a kilometer. Do we drag a sonic boom everywhere we go? No, but we do create sound waves. All sounds are vibrations. Sound is a pressure wave, and we create these waves every time we breathe, move, speak and sing.

We even make sound waves in our sleep some more than others. Our waves are faster than you might think: the speed of sound in air is about mph 1, kmph under normal conditions. I noticed that the faster I got, the smoother the ride. Suddenly the Mach needle began to fluctuate. It went up to. Bantam, Boom is making the world dramatically more accessible by….
