I've got a 5 foot egg launcher. Spring powered, and fairly accurate. I'll see if I can find it today and take some pics.

Antimatter:

PROs: Reacts with regular matter emmiting 100% photons at 100% efficiency, projectile should easily reach the Earth's escape velocity, excellent muzzle flash (once), no residue (no gun either), very little fuel needed per shot (a few billionths of a gram).

CONs: Chamber could possibly comprise of rings of high speed rotating magnets (expensive) to avoid fuel contact with chamber walls (bad), hard to transport (expensive), hard to obtain (expensive), may result in a negative effect on the Earth's natural rotation and balance (bad), very dangerous (a helmet and eye protection should be worn).

:rofl: :lol: Yes, I know. I added some things... :oh:

It's a toss-up between antimatter and hairspray... :whistle:

I did find the anti matter amusing.....:lol:

I used to use aqua net because it was cheap and came in big cans, but it still seemed difficult to get the mixture just right. When it worked, though...heheh.
I'll hafta build another and try out that orange cleaner stuff, though...sounds promising.

Most aerosols just need to be help upside-down so that you only inject the propellant. :mdr:

Harispray is really messy and leaves a lot of residue. Not very reliable...

Propane is very clean, almost an ideal fuel for spud guns... No residue and one of the more powerful fuels.

I think the best fuel would be a compressed mixture of oxygen and a fuel, but that would be very dangerous... In this case propane and oxygen - 190x mix.:rofl: I think that is 190x the volume of the chamber. I want to say it's 190psi of propane/oxygen, but I'm not sure. It's a beast. This guy has some machining skills. It can shoot a steel projectile clear through 10mm of steel.:surprised:

I may just have to try antimatter...:yipi:

I wouldn't compress anything in pvc... The compressed oxygen and propane was in a machined hardened steel chamber. Propane with no oxidizer and no pressure is about the most you can go with pvc.

That larse bloke is nuts- basically built himself an anti-tank cannon and a.... plasma cannon?! of sorts...

I forgot this one...

Hydrogen Fused with initial Uranium-235 Fission.

Pros: Extremely powerful. Causes potato to vaporize, and Ions cause the formation of "Potato plasma". Yields an expansion rate of around 345,000,000m per second.

Cons: To avoid the critical nuclear mass causing the nearest 30 miles to be completely vaporized, it is advised that you have 43 inches of depleted uranium reactor shielding, and a sustained electromagnetic field with a charge of 45 Kw handy.

AND this one...

Angry Wife chasing spud stealing Husband:

Pros: Spud can travel far distances and around corners.

Cons: Wife is in much better shape than me!

:lol:
