Tooth-Rot is made out of sugar and salt. Its like toothpaste but it rots your teeth. First get a bowl and put 10 teaspoons of salt and 15 teaspoons of sugar. Then add a bit of water (when I say a bit I mean really little). Then mix it until it becomes paste and put it in an empty toothpaste container. There! your ready to prank your friends (that was a joke don’t do it it’ll rot their teeth and I don’t think they’ll accept toothpaste as a gift).
