disappearing ink although not a favorite prank, the disappearing ink also known as invisible ink is a classic prank.Disappearing ink is a prank that doesn't bring laughs to the table but instead a few giggles might come if you use the ink in a funny form which is hard to find.My advice is if you want to become a mastermind prankster you shouldn't use disappearing ink but if you don't really care this is the prank for you.
