    I’ve got some more Christmas Science Experiments today with this lovely Christmas density jar?

    What you need

    Sugar Syrup
    Water
    Food colouring
    Vegetable Oil
    Small items to test for floating

    Other things to try:

    • Honey
    • Treacle
    • Washing soap

    How to make a Christmas Density Jar

    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.

    Why does this work?

    For a full explanation see this post.

    We’d love to see your Christmas themed density jars.
