So what does happen to a bubble at -20C ?

First you have to carefully catch one... they are really fragile this cold..
Mind you they are really pretty when they burst while you are catching one. They pop into a rain of iridescent shards of ice.

Then you'll notice it forming steam inside and out.


All of a sudden the freezing starts crystallizing it.

Then of course once it's frozen you have to stick it with your finger..

..so it'll "pop" ;)

Cool, isn't it?

(pun intended)

I'm playing some more tomorrow morning!
