On June 27th, Cool Science returned to the Basalt Regional Library to once again teach kids about liquid nitrogen and frozen treats! The age demographic for this group was mostly young teenagers, and Cool Science put on an extensive show teaching the teens about all the properties of liquid nitrogen.
Teens and parents alike were fascinated as the nitrogen evaporated into gas and shot out of a tiny hole in a Ping-Pong-ball causing the object to spin at high velocities and when flowers were chilled and shattered by the super cold liquid. One of the most popular displays was when the liquid nitrogen rode across the surface of the table gliding on pockets of gas. This is called the leidenfrost effect and happens because the nitrogen is so cold it boils and evaporates instantly on the hot surface of the table. After the show, the teens were able to make their own ice cream and Dippin’ Dots utilizing the amazing substance of liquid nitrogen.
It was another excellent event where the smaller number of teens allowed for an extensive display of the cool qualities of liquid nitrogen! The parents were more entranced by the alien-like properties of the substance than even their teens!
