If you've ever bitten into a hot chili pepper that was just a little too spicy for you to handle, then you might know how difficult it is to get the burning sensation in your mouth to go away. The immediate pain can be unbearable, and no matter how much water you drink, it just doesn't seem stop.
Now, imagine if you felt that same burning sensation all over your face and in your eyes, nose, and throat. It would be excruciating. This is the basis behind a solution known as pepper spray. Since 1973 pepper spray has been used by law enforcement as a way to subdue violent, aggressive or uncooperative subjects. Many people also use it as a personal self-defense tool to fight off attackers.
