Projects and Ideas- mixing colors with ice

Color Mixing with ice- Fill an old fashioned ice cube tray with water then add 1-2 drops of different colors of food coloring to each cube.  Try to stick to primary colors.  After they freeze, pick two different color ice cubes and put them in a zipper seal bag (tape closed if you have curious children…food coloring will stain).  Let your children push the cubes around inside the bag on the counter, or hold the bag to melt the cubes faster.  Talk about what color combinations result!
