Havin bought a metal diffuser after looking into the lovely effects you can produce, cant find any instruction on how to use it. can anyone help? Its only one of the small metal ones from the catalouge.

I too wish to re-iterate the original question. I have purchased both a plastic and metal paint diffuser, watched the instructional video accompanying the information for the metal paint diffuser (which basically says all you have to do is stick one end into the liquid and blow down the other) but no matter how hard, soft, fast or slow I blow nothing happens other than me getting out of breath! Help!
