Mixing two colors together to create a different color has a certain wow factor, especially for younger children. This experiment takes the excitement up a notch because the colors aren’t mixed together, but the same color changing effect is achieved.
Try this experiment at home with your kids and watch their eyes light up as you pour the liquid into the bowl and “create” a new color. Follow along in the video using blue and yellow food coloring or try it using other primary color combinations.
Color Changing Water Video
- Clear Drinking Glass
- Large Clear Bowl
- Blue and Yellow Food Coloring
Step 1 – Pour water into an empty glass until it is 3/4 of the way full
Step 2 – Add 1-2 drops of blue food coloring to the water and stir until combined.
Step 3 – Fill a pitcher full of water. Add 7-10 drops of yellow food coloring to the water and stir until combined.
Step 4 – Get a large empty bowl and place the glass with the blue water in the center of the bowl.
Step 5 – Next, pour the yellow water from the pitcher into the bowl. Be careful not to get any water into the glass.
Step 6 – What do you see when you look through the bowl? Is the water in the bowl yellow? What about the water in the glass? Why is some of the water green?
How Does the Experiment Work?
When you look through two colors at once, the colors “mix” together similar to how they would if you put two dots of different colors on top of one another. Because we used two primary colors in this experiment (yellow and blue), when we looked through the bowl they “combined” to form a secondary color (green).
You can also try the experiment with the following colors:
Red + Yellow = Orange
Red + Blue = Purple
