What do you think of our lovely Christmas density jar?
What you need
Small items to test for floating
Other things to try:
- Washing soap
Pour each liquid into the glass slowly starting with the sugar syrup ( add food colouring if you want ), followed by the water with added food colouring and finally the vegetable oil.
Drop a few small items in and see which layer they float on.
Do you know why they float on different layers?
Try a marble to see if it sinks to the bottom.
The science part
For a full explanation see this post.
We’d love to see your Christmas themed density jars.
