Are you looking for a unique way to learn about primary and secondary colors? “Science Guy” Jason Lindsey with Hooked on Science says all you need is hair gel and food coloring.
Transparent hair gel
Food coloring - red, blue, yellow
Plastic zipper bag
3 squeeze bottles
STEP 1: Fill each of the squeeze bottles half of the way with the transparent hair gel.
STEP 2: Using the food coloring, add a different color to each squeeze bottle. Fill the rest of the squeeze bottles with transparent hair gel, screw on the tops, and vigorously shake each bottle.
STEP 3: Open a plastic zipper bag and squeeze two different colors into the bag without mixing. Close the bag and then mix the colors to see what happens.
Red, blue, and yellow are all primary colors. If you mix two primary colors together, you create a secondary color. Mixing blue and red creates purple; red and yellow creates orange; yellow and blue creates green. Go to hookedonscience.org for more experiments that might get you “Hooked on Science.”
