Make Someone Smell Like Sour Milk.

This works best on someone who sleeps shirtless/naked

Need:

1. Warm atmosphere (works best)
2. Powdered Milk
3. Unsuspecting victim

Step 1: Set the Trap!

 1. Pour a VERY thin coat of powdered milk all over the base sheets. 
     -It should be thin enough that the target can't see the powder.

Step 2: Sleep Peacefully!

 All you need to do is wait until morning.

Step 3: Smelly!

The person should sweat during the night. If they do, they will be coated with the powdered milk, which will rapidly start to smell funky. 

Congratulations!
