Holiday Lecture 2019: Ice Cream for Science: A Legen-dairy Experience!

On Sunday, December 8, PCCM celebrated its annual Holiday Lecture: Ice Cream for Science: A Legen-dairy Experience! Led by Prof. Howard Stone, this family-friendly science show included experiments, demos, and audience participation, while focusing on the physics and chemistry of ice and ice cream. 

This year, everybody got the inside scoop! We cone-ducted a variety of experiments, including: observing what happens when salt interacts with ice, how supercooled, carbonated liquids freeze when agitated, how different liquids foam, and how ice cream reacts when pressure is decreased. Kids in the audience also had the opportunity to participate in several interactive demos, while attendees learned how they can make their own tasty ice cream at home. Check out the video of this year's Holiday Lecture below, and be sure to keep an eye out for information about next year's event! You can also take a look at previous Holiday Lectures here
