Color Morphing Experiment
Supplies:
Vegetable oil
Food Coloring
Glass or jar of water
Oil and water do not mix. They have very different densities. But putting them together can end in some cool results. First, fill your large vase halfway with water. In a measuring cup, mix 2 tablespoons of cooking oil with 3 drops of food coloring. Add that mixture to the water. Watch what happens when the water-based food coloring moves from the oil to the water. Try this with different color combinations.
Color Stacking
Supplies:
Straw
Sugar
Food Coloring
4 glasses with warm water
This one will seem complicated. Take your time. You may need to experiment with the ratio of sugar to water to make it work. .
Set up 4 clear cups. First, add sugar to them as follows:
Cup 1= no sugar Cup 2= 1 teaspoon Cup 3= 2 teaspoons Cup 4= 3 teaspoons Cup 5= 4 teaspoons
Next add 1 Cup of warm water to each cup. Stir to dissolve the sugar. Now, in each cup, add 2 drops of different colored food coloring. Feel free to add no color to one if you like. You now have 4 different color mixtures with different mixes of sugar in them. That means they will have different densities, too, and differing densities don’t mix well. You will now proceed to “stack” your colors and make a rainbow. Take your straw and cover the top with your finger. Dip the straw into Cup 1 and release the top of the straw. This will allow water into the straw. Cover the straw and again and life the straw out. You should have a small section of water from Cup 1 in the straw. Now dip the straw deeply into Cup 2 and quickly release and cover the straw. When you pull it out, the water from the first two cups should be separated. The challenge is now to proceed to rest of the cups, always moving from less dense to more. It may take some practice, and sometimes the colors end up mixing a bit. But your goal is to have a small rainbow in the bottom of your straw with your densest color at the bottom and the least dense at the top. How did it go? Did you mess up?
Here is another version of color stacking. Following the same directions for the first experiment, create 4 glasses of colored sugar water.
Now, take a tall clear glass or jar and gently pour some of the heaviest water (the one with the most sugar) into the glass first. Do the same with the other colors. Be sure to pour it in gently, maybe even down the inside of the glass so it doesn't mix into the other color. You can also try using a syringe or a turkey baster to put the water into the glass.
