I Scream, You Scream ...: A New Twist on the Liquid Nitrogen Demonstrations
Journal of Chemical Education
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!
