It shoots very well for its size with a burst disc. I can get a nail dart to stick into a tree and have an air-soft bb can go through a can (Empty).

or if you mean how it fires it is triggered by the piezo when you push on the piezo it creates a spark which jumps across the two nails in the picture which thus ignites the chemicals in the hair spray.

Do you paintball?

If so, 3/4in CPVC works PERFECTLY for paintballs. And Gatorade bottles make great chambers for about 2-3 feet of the stuff.

Trash bag burst discs...That is pretty ghetto.

It's like the garbagepicker's spudgun. Nice job on this one. You seem to have the ability to turn anything lying around the house into a spudgun.
The definition of insanity is doing the same thing over and over again and expecting different results.

Yep.
Ckman, your guns are well-made, but you should look into using decent materials to achieve the best result.
Go to the hardware store, seriously.
Till the day I'm dieing, I'll keep them spuddies flying, 'cause I can!

no I wouldn't say so they have been used as hybrids before (not at high mix's tho) and the burst discs brake at really low pressure.

In a spray and pray a gatorade bottle is fine... Plain soda bottles can be used repeatably at 100+ psi, and in all fairness, a pay and spray will hardly generate half of that.

Nice gun, I have to admit you have some major ghetto skills. I think a gun built by you with high quality materials and a bit of planning time could be good.
