Easy-to-Setup Rainbow Rain Experiment
You need the following: Water, oil, food coloring, 2 clear containers, stick/dowel, pipette/dropper
Put oil in a jar. Using a pipette, add drops of water-based food coloring into the oil.
1
Mix the water-based food coloring vigorously with the oil using a stick.
2
Pour the oil and food coloring mixture into a jar of water.
3
Water and oil don’t mix together. Oil is less dense than water, so it floats on top.
The weight of the food colouring will start pushing through the oil and fall down through the water.
Watch the rainbow rain drops!
