This activity is more of a Science experiment. While Spencer was fascinated by it, he wasn’t able to understand the Science behind it (which is totally okay). Younger kids will like carrying out the experiment while older ones will understand the explanation behind it all.
Materials Needed:
- A tall, see-through container (mason jar)
- Honey
- Light corn syrup
- Dish soap
- Olive Oil
- Rubbing alcohol
- Water
- Food coloring
- A dropper
Instructions:
Pour the honey into the middle of the jar. Be careful not to let it touch the sides.
Pour in the corn syrup. (You can color it using the food coloring.) Again, pour it into the middle of the container, not letting it touch the sides.
Pour in the dish soap.
Pour in the water in the middle of the container. Note: You’ll want to color the water with food coloring.
Pour a thick layer of olive oil into the middle of the container.
Use the dropper to add the rubbing alcohol to the SIDES of the container. We just used an old bowl. Note: You’ll want to color the rubbing alcohol with a different color of food coloring.
If you pour the rubbing alcohol straight in, it’ll probably pick up the food coloring you used in the water and your rainbow will be ruined.
Explanation:
Different liquids have different weights (densities). Everything is made up of tiny things called molecules. Some of liquids have a lot of molecules in them and some of them only have a few. The density of a liquid determines whether it will float on or sink in another liquid.
