This is a very simple prank that has a nice pop when steped on and is reloadable.
Oh and this is only my second intructable so merry christmas
Step 1: What You Need
1.string bomb/cracker.(fairly cheap and similar to confetti popers, got mine from cannonfuse.com at 69cents for 36)
2.metal wire coat hanger.(plastic ones will not work, plastic coated metal might work)
Step 2: Bend the Coat Hanger
Take the hook of the hanger and use your hands to bend it arond 90*(degrees)like shown in the picture
Step 3: Make Groves in the Hanger
Use the wire cutters to make grooves in the hook of the hanger
Step 4: Bend the Hanger
Bend the hager as shown in the picture and lock it in the groves
Step 5: Add the String Bomb
Tie one end of the string to the hook and the other to the rest of the hanger.Do not give the sting much slack to make shure the cracker pops.
Step 6: Blank
To set it off step on it or you could possibly throw it.
