Q: How do you make a fishy theme with oil and water?
A: Here we have an easy oil and water experiment with a fishy theme! STEP 1. Fill the small cups with water. STEP 2. Add 2 to 3 drops of food coloring to each cup. Stir with spoon. Notice what happens to the food coloring. STEP 3. Next fill the larger cup with baby oil. You don’t need to fill it too full – halfway is fine. STEP 4.

Q: Why do oil and water not weigh the same?
A: That causes oil and water to form two separate layers. Water molecules pack closer together so they sink to the bottom, leaving the oil sitting on top of the water. That’s because water is heavier than oil. Making a density tower is another great way to observe how not all liquids weigh the same.
