Poof! Magic Matter

Food is ideal for experimenting with changes in matter. Demonstrate how a solid can magically dissolve into a liquid with cotton candy! Drop cotton candy into water and watch it magically disappear. Try different temperatures of water. Make a prediction and a hypothesis about the temperature of your liquid and your candy floss. Have kids draw and label the components of the experiment in their science notebook. Is dissolving cotton candy a physical or chemical change? - Physical 

If you remove it quickly, before it dissolves completely, it will actually turn back into a solid! Check out the video below by Mr. Mario Mind! Also, try dropping a large ball of cotton candy in water, and watch it disappear in seconds! Kids will be amazed! Try mixing different colors of cotton candy to change the color of the liquid.
