This is an Instructable that is devoted to the effective and messy prank of chalk dust in a hair drier.

Step 1: Materials

This is a very simple prank that only consist of 3 things: 1) chalk dust or chalk 2) a hair drier and 3) a victim >:).

Step 2: Prep

The first thing you have to do for this prank is locate your victims hair drier. Once you have located the hair drier just add a some chalk dust into the front. Or if you only chalk, grind the chalk with something into a very fine dust. Remember a little chalk dust goes a long way and if you add to much then you could cause the hair drier to over heat. Once you have added the chalk dust to the hair drier hang it so that the front is facing up.

Step 3: Sit Back and Wait

The final and personally my favorite step is to just sit and wait until your victim steps out of the shower and turns on the hair drier to dry his or her hair off, only to be covered in disgusting chalk dust. After the prank is pulled run in to see the aftermath and yell "April Fools!"
