Science fun and Booms – Dry Ice Demos!

Jeff Rosenblatt returns this week with a Dry Ice Demos! The Dry Ice Demo is relatively easy and low maintenance. It only requires a few materials – dry ice, Hot Water, and a large container with a lid!

So what is happening?

The temperature of dry ice is -109 degrees F, while hot water can be over 100 degree F.  As the hot water is poured over the frozen carbon dioxide, this temperature difference causes the dry ice to sublimate rapidly – sublimation is when a solid changes to a gas.  When dry ice sublimates it expands 554 times in volume.  This rapid expansion from a solid to a gas builds up enough pressure to pop the container lid off with a loud boom!

We’ve got slow-mo and full videos for you to check out this week.
