IMO it's too much trouble to go through that and the results woudn't be the same.. i would just buy a real foam gun knowing it's a one time purchase that's money well spent.. i've had mine for many years and do not regret buying it one bit...
Cool idea if you have a cordless blower your not using,would be fun just to try
Foam looked thick
I think I could tweak it using brass fittings to accept the bottle
