Oil And Water Flip Density Science Experiment
In this fun and easy science experiment for kids, we’re going to try and use density to flip oil and water.
- Two small clear plastic cups that are the same size
- An empty cereal box
- Cooking oil
- Baking pan
- Optional – Food coloring
- Cut a square of cardboard that will fit over the top of the cup.
- Fill one of the cups all the way to the rim with water. Optional – Add a drop of food coloring.
- Fill the other cup all the way to the rim with cooking oil and place it in the baking dish.
- Put the square of cardboard on top of the cup filled with water.
- Hold the cardboard firmly against the cup with the water.
- Carefully turn the cup of water upside down and place it on top of the cup filled with oil.
- Now slowly pull out the piece of cardboard.
- The water will go to the bottom cup and the oil will move to the top cup.
How it Works:
This is a great science experiment to illustrate density. Once the liquids are allowed to mix, the less dense oil will move past the water and transfer to the top cup.
Make This A Science Project:
Use baby oil. Use two types of oil instead of water. Use warm water.
