Middle School/High School
Ready to be the coolest teacher at your school? Just kick off your sublimation lesson with this crowd-pleasing demo.
A special effects staple on concert stages everywhere and often used in ice cream parlor freezer cases to create that smoky-cool effect, dry ice (the solid form of carbon dioxide) gives off its signature smog when it undergoes the process of sublimation. Sublimation is when a solid absorbs heat energy from its surroundings and turns directly into a gas, skipping the liquid phase.
Watch as we show you how to re-create the ice-cream parlor-effect in your own classroom and demonstrate sublimation in action. All you need are a few simple ingredients - dry ice, water, and bubble solution.
