Floating experiments

The lardberg

Because an iceberg floats in water, will frozen olive oil float in regular olive oil?

Ingredients and equipment that you will need

An ice cube
A cube of frozen olive oil. Unfortunately it has to be olive oil because cheaper oils won’t freeze in a domestic freezer
Olive oil

Method and further information

Icebergs float. If you put an ice cube in water floats to the top. NO other chemical does this.

Freeze olive oil and put it into a cup of liquid olive oil you will see that it sinks.

Be careful – you should ask an adult to help you with these experiments. Do your experiments in old yoghurt pots, jam jars or bottle tops. Don’t use cups or glasses in case someone thinks it’s a drink.
