How good is the P.A.C 2 off of Xinventions.com? I need to build it for my science fair and I have a couple questions.

A) Safe?

B) How much does all the materials cost?

C) Easy to use?

If you can answer this I will appreciate it very much.

Thankya.

EDIT: I have the same questions about the P.A.C 1, because I want to use that with my friends just for fun.

well it's a sprinkler valve so it'll be powerful but not insane.

It's also a cheap way to make a decent cannon. He didn't mod the valve, if you do it's more powerful

Thanks!

About how much would it cost though... Just estimated price.

You've helped loads!

Hmm.. a sprinkler valve is about $11 at lowes. All the other pipe and fitting can't be more than $10.

If you want to mod it, a blowgun is another $5.

Not really a lot. The fun of blowing stuff apart is worth it.

Dont forget primer and glues.This design is simple and it will be fun.Plus you dont have to make it to look just like that.Do a bit of your own designing.

the pac2 was my first gun, i went and got my home depot receipt for you, and following the exact plans, it cost me $52.97 becasue i was starting from scratch, and i subbed out the 2.5" for 2"
