A couple jobs ago I was working in an office several years ago and one of the owners bought an airsoft gun and brought it to work to shoot people with, needless to say, after everyone armed themselves and a computer monitor was broken, they were quickly outlawed. But we still had tons of airsoft ammo in various corners of the office. So I built one of those bottle cap and balloon projectile launchers from a soda bottle I was drinking from and a balloon left over from an office party. Those things work great and are very accurate. You aren't going to take out any Zombie's with one, but if you are trying to knock a squirrel out of a tree using some small rocks, they would very very likely do the job. Also a great choice for office wars
