This is a handgun I made from a pill container and a 1/4 inch piece of copper piping and a piizo ignitor. It has massive recoil and has a hell of a lot of power. It can fire AAA batteries through cans easily!

haha, thats pretty sweet, what is with you and the extenders? What exactly do they do? Is it a silencer or is it for looks
By the way, your barrel is kind of pointed upwards, it must have seen a female gun

Yeah! The extenders actually work really really well. Basically it eases the difference in pressure. Cause when all the gas comes out of the barrel at those high velocities it expands extremely fast. This just gradually releases the pressure, the holes are very important to. Silencer are illegal were I live and also difficult to make for minis so extenders are the top choice. And the barrel became upwards after the first time we fired it and we cant get it back. The recoil pushed it like that, sounds weird but we were too shocked to notice at the time!

Are you using aerosols or propane as a propellant? Nice compact mini, dude.

Thanks! I like to use propane but have found that one squirt of cologne does the trick. Only thing is it leaves a nasty oily residue and after a while shooting stops working and i need to clen the chamber.
