Ghetto Weapons thread: murder on the fly!

[Lantern]

I was talking with some people on the IRC, and for some reason i suggested that you should be able to make a blowgun out of a hollowed out pipe and a syringe, with a 50% chance it will fuck up and kill you, or something. Then i got to thinking, why aren't their more craftable ghetto weapons like the zipp gun? So what are some fun/easy to sprite and code weapons you can make from shit just laying around the station?
