Knackster, thank you. :) I was wondering about that date myself. LOL! I first saw it in 1976ish. HINT FOR DOING THIS: Try it first on the tabletop (or maybe on a towel in a small pot or soupbowl), at least partially, so you get a feel for what you'll be needing to do within the bottle.
"Nowadays,... nitrous oxide is the largest man-made cause of ozone depletion"Interesting. I believe airplane take-offs produce a huge amount of NOx, no? I'll have to dig through my files as I did some research at one point in a discussion about smokers polluting the air with NO or NO2, and was comparing it to the amount put out by planes.- MJM
