WHAT TO EXPECT

The colors will change at different rates depending on the color, the liquid, and the temperature of the solution.

WHAT’S GOING ON?

The solid candy melts into the water or other liquid to create a solution that has its own color. Different pigments (solids used to create colors) dissolve (enter solutions) at different rates.

QUESTION THIS!

• Does it make a difference if the colored candy has a flavor or not?

• Do different candies with the same color dissolve at the same rate?

• What happens to candies that have writing or other symbols stamped onto them?

• What will happen if you place two or more candies of different colors in the same dish? Can you make new colors this way?
