Subject: CO2 release from soda

Post:
A quick note...I changed the subject line so that this create a new
thread. Many people may have dropped of the previous thread...and this
makes this more searchable later.

My guess is the rapid cooling somehow weakens the walls of the bubbles,
thus allowing them to pop and release the gas. In fact, I'm willing to
bet that any abrupt change in temp causes the bubbles to do this. Pour
some soda onto a hot skillet and see what happens. Be safe while you do it!

"Get Fuzzy"

Bucky, the arrogant cat: Aaaaaaaa!

Rob, the geeky owner: 11:55. Right on time for his nightly freakout.

Satchet, the lovable dog: Ever notice how he runs circles in the same direction?

Buckey: Yaaaaaaaa!

Rob: Maybe the coriolis effect works on cats, too, eh?

Satchet: Ha, ha! I have NO idea what that means!
