The point is I need to get a proper propane tank + adapter for it.

Do you guys know some good websites selling that (shipping out of US) for a fair price? Or got some other suggestions?

What about a can of lighter refill?

You will be making a vid eh?

When will it be done?

Be careful m8.

we want pic and vids !!!!

And what if its hairspray?
My fan will get sticky as hell then

Now a name for the projectile!:

When I fit a fan that covers the whole diameter of my chamber, how can i spray in gas from the back then?

Well go ahead, show us that it works and we will follow.
