3. Creative surprises: The thing I love most about high-fire pottery is that in a reduction firing, you never know how the glazes are going to come out, exactly, until the kiln is opened after the firing. Each firing was like Christmas, full of ooohs and aaahs and "look at THAT!!"s. I'm glad you get the same joy from glass work. It's something I've always been interested in, but, well, I'm interested in enough other things at the moment.
wondered if it worked? i take it you didn't see the movie. being a slightly different sort of geek, i wonder *why* it works, 'cause the the answer seems like a fine way to make it work better. ;)
acid + base = explosion. :) my guess is that the carbonic and phosphoric acid is combining with the menthol in the mentos. I don't have any ingredient packages handy near by to check, nor my trusty CRC to check the acidities.
My assumption was actually that the coating on mentos, for some reason, provides a lot of nucleation sites. They feel a little slick and a little powdery; it made sense to assume they had lots of convenient microscopic pits.
I'm actually not quite sure where the spiral came from. I put in a bunch of dots, but nothing spiraled on purpose, anyway. I think I may've created it smoothing out the shell in a circular motion. Glad you're amused.

I don't actually know, though.
