instead of doing all that tricky stuff on your first cannon just put a bike pump valve in the side of ur chamber and use a small bike pump to mix your fuel its alot cheaper and u never havto replace any batteries :lol:

Thats a bit tedious and annoying to do that, plus it requirs you bring a pump. It also doesn't mix as well as a fan.

And if you pump it too high and the spud is tight enough in the barrel that it doesn't move, you have yourself a hybrid...........

Oh and you can't use it to make turbulence in the fuel like you can with a fan. (leave it running when you fire it)
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.

I still can't see the NET benefit of using a hand held camping fan over a fan for cooling electronic devices. The mounting, compatability, contained blades, compactness, and existing wiring far outweigh the only? benefit of the hand held fan's superior cfm rating.
Just my humble, objective perception of the differences of the tools.

Hence the camping fan :P
Ha I'm sorry for the insignificance of this post, but MrCrowley that just made me laugh! Ha it's just all so obvious now! Camping...Fan...Use it when your camping! Ha :D
