Dippin Dots ice cream was started in 1988 by a research microbiologist named Curt Jones. Basically, he had the idea to take a process used frequently in research and use it with ice cream. Here's what they do:

They take little tiny drops of ice cream liquid and drop them into liquid nitrogen (freezing it crygenically). Since liquid nitrogen is so cold, the droplets freeze super fast and stay in that nice little BB shape. Of course, the ice cream has to be kept super cold until it is eaten so it doesn't melt into a puddle - this is done with dry ice (solid CO2).

Some (unconfirmed) facts about Dippin Dots that I found online: Dippin Dots makes all its ice cream at a single factory in Paducah, Kentucky - the factory uses about 10,000 gallons of liquid nitrogen a day to make about 5000 gallons of ice cream.
