I also wonder how they make Dots, the ice cream of the future that looks like styrofoam beads.
I used to sell Dippin Dots when I worked at the zoo in St. Louis. They are made by bubbling liquid nitrogen through the ice cream to flash freeze it into those little beads. They have to be stored at really cold temperatures or else they'll melt and lose their novelty, hence why you can't just buy them at the grocery store.
