![grab](../web_assets/superdoit/do_it_grab.gif)
- a clear glass or jar
- water
- vegetable oil
- salt
![how?](../web_assets/superdoit/do_it_how.gif)
- Put water into the jar until it is half full.
- Pour vegetable oil into the jar. The oil floats on the water.
- Take a spoonful of salt, and pour it into the jar all at once. It sinks through the oil, and down through the water, taking some oil with it.
- Keep watching as oil blobs slowly begin to rise up through the water. Try adding other things, like sugar, sand, or flour.
