HELLO.
So for anyone who was an athlete at one point, you may know about smelling salts.
Smelling salts are usually used by boxers and MMA fighters to wake them up after being knocked out. Various athletes also use them to wake themselves up a little bit.
WARNING: Don't do this at home or unsupervised. While not dangerous, kids shouldn't do this. I did this simply for comedic purposes. And because I'm kind of an idiot.
