Ooh, that does sound fun! Do they do it with a carbonator?

I like edible experiments, especially as I get better at them! The pizza was fun to improve upon and practice, but the results weren't always delicious. (AndI am now firmly convinced that calzones were invented by someone who, like me, had trouble sliding the pizza from the paddle onto the stone and was just like, "No, it's SUPPOSED to look that way!") Looks like the soda is going to be the same way.
