I actually HAVE added a propane tank w/ a clear hose running from the front of the gun into the back of the top chamber now. All the appropriate fittings and valves make it look pretty good. Unfortunatley, this propane rarely if EVER ignites! I have 7 sparking points inside of the chamber, and it is...

The barrel is 4ft long @ 1.5". I did all the calculations to get "exactly" a 1 to 1.5 ratio.

I'm sure technically it is better to have it with more voltage, but the difference is probably negligible. I use a 100,000 volt taser in my gun, and it has 7 spark points! Makes a very nice explosion!

Well, the screwdriver is so you can dismantle the gun! The hose clamps can come off, and by disconnecting the wires (not pictured) the gun be broken off into 3 pieces. Also, the front-most handle can be rotated 90 degrees if one so desires. I forgot to mention that before. Also, the storage space is...

Here are some pictures of my latest creation, the V-C4. It has a 100,000volt ignition, 7 sparking points, a 1:1.5 ratio, two handles, saftey switch, power switch, battery gauge, storage compartment, removable barrel, and much more! Tell me what you think! And yes it fires great! (these pictures are ...
