A powerful, simple, and reasonably accurate "office weapon". DANGEROUS!!!!!

Step 1: Step 1- the MATERIALS!!!!

You need:
- A standard party sized balloon
- AN empty scotch tape roll, a short and wide pipe scrap watever.. any short tube with the width about the opening of a scotch tape roll
- Masking tape (Electrical works best)

See? only 3 items! easy enough!

Step 2: Step 2- Building It

Cut off the neck of the balloon so there is the large bottom left. Stretch it over opening of barrel, and make it go about halfway up. then, carefully apply masking tape- 2 times around the part where the balloon ends on the barrel, careful not to let the tape go onto the part of the balloon not on the barrel, or go off the barrel.

Step 3: Step 3- UR DONE! Ammunition

Best Ammunition:
Air Rifle Pellets
Lego Mini Lights
Beads
Gobstoppers
Toothpicks- if not fired correctly, may damage peas shooter

Remember again, this is a weapon and highly dangerous! DO NOT FIRE AT ANY LIVING THING!
