  • Making Ice Cream Cooler… With Nitrogen
    Kirsten Sanford
    Host/Producer, Food Science

    Nitrogen is an abundant element on Earth and beyond. It makes up the majority of our atmosphere. However, when pressurized into liquid form, it is extremely cold. The characteristics of liquid nitrogen make it useful for many applications in research, technology, and the kitchen. Dr. Kiki elucidates how one can get their hands on liquid nitrogen, fun that can be had with it, and how to play with it safely. Leo gets to eat ice cream. Sounds like a fair trade, right? Dr. Kiki also talks about some of the more interesting applications of liquid nitrogen: cryogenics and as an alternative energy option.
