Fascinating Trivia
The first human-made object to break the sound barrier was a whip. As the energy increases from the handle to the end of the whip, the energy is moving beyond the speed of sound at the tip. That’s why a whip makes such a loud cracking noise.

That is fascinating! Who would have thought. My youngest son brought a whip back from a trip he made to Spain. His dog is so funny, if she sees him reach for it (he's never hit her with it, of course, but he will crack it)anyway, all he has to do is reach towards it and she begins talking to him in her own way and running between Grandma's (me) knees.
And perhaps also a bow and arrow.
African or European?
