B.A.C. Gun / battery cannon

Unread postAuthor: Brooner115 » Mon Jan 29, 2007 6:03 pm

This is my B.A.C. Gun it means Battery Annialating Cannon. I normally shoot batteries but its so powerful that once i shoot them they bend and sometimes LEAK THEIR ACID!!!! So i took a trip tp my local Michael's craft sftore and found some metal marbles used for decoration but their the same diameter as a battery. THEY DO SOME MAJOR DAMAGE!!!!

Its just a regular ballvalve air cannon that i pump to 90 PSI and tear holes in soda cans with. Heres the pics ENJOY

SORRY no damage pics... yet

Hehehehe, nice. I love small objects moving at high speeds. If you aren't taking that above 90 psi, you should put a moded sprinkler valve on it; more velocity and easier to fire.
Barrel looks like someone sat on it, but who cares.
Those metal marbles look devastating. If you can make sure that they bounce in a safe direction, try cracking a cinder block with one.

I wonder how much deeper the ocean would be without sponges.
Right now I'm having amnesia and deja vu at the same time. I think I've forgotten this before.

Good attempt.

I've smashed dozens of batteries apart myself. Disposing of the ones that are leaking is always difficult, so I'm unsurprised that you searched for new ammo.

A larger chamber would do nothing but add noise output to this gun.
