- a tall glass jar
- syrup
- cooking oil
- a cup of water
- a grape
- a small piece of plastic
- a cork
![how?](../web_assets/superdoit/do_it_how.gif)
- Pour two cups of syrup into the jar.
- Slowly pour two cups of cooking oil into the jar...it should float on the syrup.
- Pour the cup of water into the jar of syrup and oil. It will sink below the oil, but float on the syrup. It forms a whole new layer!
- Grab the cork, the grape and plastic and drop them in! Will they sink or float?
