Cryo Cream!

I was on a trip to San Francisco last week and stayed at a hotel near the airport for the meetings (didn't even get into the city!) The last night there, I went out to dinner in Burlingame with some friends. The hotel had a free shuttle and it dropped us off right in front of a place we all knew we had to try: Cryo Cream.

 Cryo Cream makes your ice cream fresh after your order it using liquid nitrogen. Pick your flavor, everything gets put into the machine and then the liquid nitrogen is added to freeze it in a puff of steam.

 Water vapor from the atmosphere condenses and forms ice on the very cold tubes carrying the liquid nitrogen.

 And the back wall is decorated kind of retro-sciencey.

Somehow the ice cream did not get a picture taken...it went too fast. What a great concept for an ice cream shop with uber nerd appeal!
