You put the fan about halfway into the chamber. It doesn't get in the way. The whole idea is for it to come in contact with the fuel and spread it around.

Nice Cannon. That's a lot of tape though.

I'm glad to see another cannon using a long nosed lighter as the ignition source.

I wish i had somewhere to get ABS pipe. My hardware stores don't sell it.
