That's cool

Ever wanted to make ice cream in a hurry? I saw a video on Martha Stewart months ago where a guest chef made ice cream with dry ice! I thought that would be a perfect last project to do in Rose's class. I decided we would have to do a 'dry' run at home first. It is pretty simple, you make the custard (milk, eggs, sugar and flavor) put it in the stand mixer, smash up about 2 cups of dry ice as fine as you can and start mixing it into the custard. It will bubble and fizz while freezing in about 5 minutes!

Oh, yes and it looks like the mixer is on fire! These shots don't show when it is really subliming, but the kiddos were suitably impressed.

I did some simple experiments too, putting a chunk in a bowl of water so the vapor boils out all around, making smoking bubbles with dish soap and water, and blowing up a balloon (it was over the mouth of a bottle).

All finished! It was a little strange and carbonated at first but now it just tastes like fluffy vanilla ice cream. Another reason to make the ice cream the kids are going to eat is to make SURE there are no more chunks of dry ice hanging around.

Frosty!
