Rainbow Rain

This rainbow experiment is so cool, and I hope it will blow your minds as much as it did mine. Watching the bursts of color fall through the water is so mesmerizing, and I would watch it all day if I could. I hope you enjoy this experiment!

What you need:

• A jar
• Water
• Oil
• A bowl
• Food coloring
• A spoon

Steps:

• Pour the oil into a bowl and add your favorite colors of food coloring.

• Using the spoon, stir together all the droplets of food coloring. Make sure to do the next step quickly so the droplets do not start combining to form one big, black blob of food coloring.

• Fill the jar with water.

• Pour the oil and food coloring into the jar. Wait a couple seconds, and then watch your rainbow rain fall throughout the jar!

What caused this rainbow rain?

Water and oil cannot mix because water is polar while oil is not. Food coloring is water based, which means it is made with water. When you pour the food coloring into the oil, it cannot mix with the oil. When you pour the food coloring and oil into the water, the food coloring separates from the oil and mixes with the water.
