How much itching powder should I put in someone's bed for a prank?

To prank someone effectively, you should put about a tablespoon of itching powder in their bed. The amount of powder you use should be enough to spread evenly throughout the sheets and mattress so that it does not feel too harsh when they experience the sensation.
