|Making a density toy
Oil and water have very different properties. They do not mix and their densities are different. Oil is less dense than water and will float on the surface of water. These properties make for very interesting experiments.
What you will need.
- 2 specimen jars and 2 eye dropper tops.
- olive oil or rubbing oil (Baby oil)
- food dye.
- hot plate

Research the following words
1) Do oil and water have the same surface tension? Explain.
2) Why are the bubbles of water floating in the oil smaller than the bubbles of oil floating in the water?
