5 UNLIKELY SOUND BARRIER SMASHERS
1 WHIP IT
In 1958 it was discovered that the loud crack created by snapping a bullwhip is actually a tiny sonic boom created by the tip of the whip breaking the sound barrier.
2 NO TROUBLE FOR TOWELS
An infamous high school locker room gag, whipping a towel at an unsuspecting teammate and causing a cracking sound is the result of the tip of the towel travelling faster than sound.
3 FLAG THIS ONE
A flag on a flagpole buffeted in a strong wind can cause a sonic boom when its leading edge goes supersonic.
4 A BRUTAL GAME OF PING PONG
In 2018 Mark French and a team from Purdue University created a ping pong bazooka capable of launching these light, hollow plastic balls to speeds exceeding Mach 1.5.
5 FELIX IN FREE FALL
In 2012, Felix Baumgartner leapt from a balloon 24 miles above New Mexico. Not only did he break the then-world-record for a free fall, but travelling at 843.6 miles per hour, or Mach 1.25, he also broke the sound barrier.
