Sonic Booms
Sonic booms are surprisingly easy to generate. All you need to do is hop into your fighter jet, reach a decent altitude, and then go full throttle. Depending on where you live, you might need to call up your government contact person and give them a heads up. And for those of you who are especially financially wealthy, you can use a state of the art whip. That whip crack sound occurs when at least one part of the whip has reached supersonic speed. And that's basically a sonic boom.
