Subject: RE: Alternative fog substitutes?


I'd use the liquid nitrogen in a bind myself; however, if you have a "spencer's
gifts" nearby, they sell small bottles of "fog juice". Also, there's a new
toy called a "zero blaster" which is a small, gun-like rendition of a smoke
ring cannon. I would imagine that most toy stores sell them. And I'd imagine
that they sell small quantities of 'refill' for it.

'hope that helps!
