1. How interesting. I would never have thought to add dry ice like that.

2. I've seen videos of people making ice cream with liquid nitrogen

Dry ice works on the same principle, but is less dangerous to work with and more readily available. I don't make ice cream very often, but I think I'll try this the next time I do.

3. I've done the same with liquid nitrogen

It's sort of a rite of passage for young astronomers. "Slave! Make me ice cream!" said the professor...

I didn't mind, it was fun. But I realize LN2 is not accessable to all. We always have 100's liters on hand to cool the cameras. May as well use some in the kitchen, eh?

5. I did it with LHe at our department picnic when I worked at BNL..

My boss was a little twitchy about the cost, but it was even more impressive than LN2...I overestimated how much I'd need and stalled the mixer, instant rock-hard block of the creamiest, smoothest ice cream I've ever had
