Simple Pea, Bb and Pencil Shooter

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:)

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.

Take the bottle and cut it off about 1cm from the top as shown.

Cut the end of the balloon off as shown.

Fit the balloon over the grooves of the bottle.

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.

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:)
