tissue, taped in different spots can give you a very good direction of where air is moving. and you can leave some tissue pieces laying around to see where they move to. that is our material of choice. plenty of it and it weights very little. no mess

good point...actuall smoke from insentse(or however you spell it) works well because it is thick...unless you like to smoke alot...

I will save my packing peanuts..and terrorize one of my distributors with it..they really like using lots of it when shipping product...maybe I should some day fill their car with it just for fun..right up to the top [img]smile.gif[/img] ))
