There’s an old video on YouTube of an older man with a slingshot blasting hand tossed coins out of the air.
Theres also a what not to do vid of a guy shooting a 1/2” ball bearing at a target in front of a plywood back stop. It ricochets straight back and smacks him in the forehead, its pretty gruesome.
Zach Fowler, winner of Season 2 of the TV show Alone is a friend of a friend. He has several wooden burned matches on display in his house. He lit them with his slingshot.
