A few weeks ago my aunt’s boyfriend surprised the kids by bringing over a couple of bags of dry ice while he was passing through town.
I’d never experimented with it before myself, so we all had fun.
What is dry ice?
Dry ice is frozen carbon dioxide. When it “melts”, it turns back directly into a gas!
Safety tip: Don’t handle dry ice with your hands or allow bare skin to touch it. We used tongs to handle it, or you can use thick gloves or oven mitts.
Here are a few different experiments you can do with kids with dry ice.
One of the first things we did was put a few chunks in a zip top bag to see how it would melt. The kids all predicted that it would melt into liquid.
Put a coin in it
They also had fun watching how quickly a coin held against the ice melts it!
Make it burst
Put some warm water in a small baggie. You can add food colouring if you want! Then add a few pieces of dry ice, seal the top, and watch what happens! You can add dish soap to the water first for a bubbly explosion!
Make it steam
The kids enjoyed filling a small kettle with water then adding the ice. It sounded and looked as though it were boiling water, ready for tea!
Make it bubble
By far, the kids enjoyed added the dry ice to soapy water more than anything else. Big bubbles that they could hold!
