How far and fast dooes it shoot.

So when did this go on the terminator? lol

How did you make the handles, I was thinking of a simular model to mount on my go-cart.

And could you have the ignition source on the handle? Just wonderin.

Can you use a scuba tank for the air?

Could you use copper for the barrel, and is the magnet on the outside or inside.

So all it is is a basic spud gun, sized down and made with copper?
