Liquid Nitrogen Demo: National Engineers Week 2016

On February 25, 2016, Katie Wyttenbach ’11 of Air Products and Chemicals, Inc. returned to Lafayette to hold a liquid nitrogen demonstration. Ms. Wyttenbach first informed students of the many professional uses of liquid nitrogen and of its hazards. Afterwards, she gave exciting demonstrations illustrating its diverse applications, its properties, and some ways in which it can be extremely dangerous. Some of the many demos included: levitating metals by altering their magnetic properties, condensing air immediately on contact, and almost-instantly removing oxygen from a closed space (shown using candles). At the end of the event, liquid nitrogen oreo ice cream was created for students to sample!
