Ice Art

You will need:

A small plastic container such as an empty butter tub/yoghurt pot or a silicon cupcake case.

A natural object such as a small pebble, shell, leaf or small plastic figure.

Fill the container almost to the top with water.
Carefully drop your object into the water – does it float or sink?
Place the container in the freezer overnight.
In the morning remove the container from the freezer – what has happened to the water? Is it solid or liquid? Is the container filled to the same level?
Gently remove the container and place the contents into a larger container that is deep enough to hold the water. You could use the sink or put it outside if that is easier.
Record what happens throughout the day – you don’t need to watch it all the time, just check it every so often.
How long before your object is free?

You may like to freeze a piece of string into the water to allow you to hang it up as a garden decoration.
