In this Instructable, all you need is: -an egg -a door
Step 2: Pull The Prank
Tell your victim that you are going to do a magic trick on them and tell them to put their thumb and index finger through the crack on the side of the door opposite the door knob (the crack that usually has 2 hinges). Assure your victim that you are not going to smash their fingers in the door. Place the egg between their fingers and tell them to not let go.
Step 3: Leave
If you know the person very well, then you can leave for about 3 minutes (at most). Come back and say "April Fools!!" if they hadn't already given up and let the egg drop and break. You can now take the egg out of their fingers and hope that they aren't burning mad. Have fun with this prank! ;D
