Abstract

Instant ice cream is made using liquid nitrogen and ice cream or sorbet mix.

Placing fruit and rubber balls in liquid nitrogen is a staple in the cupboard of demonstration activities. In case you missed it, Kurti and This-Benckhard (i) have suggested a culinary delight that makes a wonderful addition to any outreach program; instant ice cream. Stirring together equal volumes of ice cream or sorbet mix and liquid nitrogen gives the abundance of air bubbles and minute ice crystals that produce a smooth, light consistency. Rather than as a demonstration, we incorporated instant ice cream as a hands-on activity for middle school students at the end of our “Week of Chemistry” programs this summer, with delicious results!
