1Make some colored water.

Place about ¼ cup potable water each into small bowls. Add 5 or more drops of food coloring to each bowl. Mix well.

Test the color intensity of the water by painting on plain white paper. If you want the color to be more intense, add a few more drops of food coloring until you achieve the desired color.

2Put into an ice cube tray.

Put the colored water into the sections of an ice cube tray.

As a color learning and mixing activity, just prepare three colored water solutions in Step 1, the primary colors—red, yellow and blue. Spoon in the colors into each tray section by pairs to come up with the secondary colors—orange (yellow + red), green (yellow + blue), and purple (blue + red).

3Place the tray in the freezer.

Place the ice cube tray in the freezer.

4Prepare the handles.

While waiting for the ice cubes to freeze, prepare the handles for the ice cubes. You can use disposable wooden ice cream spoons or cut popsicle sticks in half.

5Add the handles.

Check on your ice cube tray after about 30 to 45 minutes. When the colored water is half-frozen, stick a handle into the center of each ice cube.

6Put back in the freezer.

Put the ice tray back in the freezer.

7Remove from the freezer.

After a few hours, check on the ice cubes. When they're solid frozen, take out the tray from the freezer and allow it to stand at room temperature for a few minutes. Twist the ice tray slightly to loosen the ice.
