Colorful Patterns in Melting Ice
Have you ever wondered why ice cubes in your cold drink become gradually smaller, or why their surface becomes smoother as they melt? Does ice always melt this way?
In this activity, you will use water balloons to create giant ice balls and observe how they melt. Can you predict the effect a bit of salt will have on your giant ice ball?
