I am sure anyone who is interested in office weapons has seen this design a hundred times already but i thought i would post it anyway, hope everyone likes it:)
Step 1: Materials
For this instructable you will need a bottle (i'm using a soda bottle), a craft knife or scissors, a balloon and some dried peas or bbs.
Step 2: The Barrel
Take the bottle and cut it off about 1cm from the top as shown.
Step 3: Step 3
Cut the end of the balloon off as shown.
Step 4: Another Step
Fit the balloon over the grooves of the bottle.
Step 5: FINISHED
Now pull the balloon through the top of the bottle as shown. To fire, drop a pea or bb into the balloon, pull it back and release.
Step 6: Pencil Ammo
This is an extra tutorial for the pencil ammo. You will need a pencil(obviously), a nail and some wool or string.
I really don't think i need to explain this step. Fire it the same way as the bbs. Please use this with caution and do not fire this at humans or animals:)
