CARTERVILLE (WSIL) -- The Weather Academy stopped visiting schools a while ago, but the still have more science to share.
Only 3 items are required for the experiment:
- Table Salt
- Metal can
- Pour ice in can
- Pour Salt over ice
- This will melt the ice and create a really cold salt water solution inside the can. Melting ice takes heat energy away from the environment around it, so the temperature of the solution will dip below freezing.
- If you wait long enough, the cold solution inside the can will make the outside of the can cold enough that it begins to form frost.
