yeah that looks like a good system but isn't 3 or 4% of the chamber meant to be filled with butane in gas form not liquid form? I think the butane liquid to gas ratio is about 1:200.

I've seen the basic hairspray design and i wanted to build something that would put the right amount of gas in the chamber. I don't have the time to ship all the parts for the metered propane system so i came up with my own idea. I found these butane refills :arrow: :http://www.bernzomatic.com/item....
