Where science and tech meet creativity.

I heard the coolest thing today. One of my students, who wintered in North Dakota, reported than at temperatures below zero F, when you blow soap bubbles, they freeze and crumple. If you are some where cold, can you please go out with a little kids thing of soap bubbles and see what happens? The physics is straight forward – the soapy water is so so thin that it freezes almost instantly. At the same time, as the air inside (initially warm from your breath) cools, it shrinks. Since the soap bubble has now frozen, it can’t just shrink, but instead crumples.

I really want to see this, but its just above freezing here 🙁

EDIT: Steve sent me the most amazing photo. It is strangely beautiful. I’ve included it big for you to enjoy!bubbles_9999_6.JPG
