@Canndo I really don't think you meant the venturi effect. It took a while but I think I found the equation I was looking for and a summary, pertaining to a canister of compressed air but it's the same principle as with the N20
I think that makes sense. I'm not trying to be a smartass but I was fascinated with the effect since a kid deliberately pressed a ventolin nozzle against my wrist and pumped it till it froze the skin, which left a really nasty wound...
Mjetta there are loads of girls on this forum- myself, Urca, WinterWoman, Ella Jean etc... Lol that avatar is the character Nancy Botwin from the t.v show 'Weeds'. *giggle* She is pretty though.
