Welcome to our Halloween density experiment.
What do you think?
What you need
Treacle
Golden Syrup
Water
Food colouring
Vegetable Oil
Small items to test for floating
Instructions
Pour each liquid into the glass slowly starting with the treacle, then the golden syrup, 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.
You can see below that we have a plastic bug floating on the top, a LEGO brick floating on the water and a paper clip floating on the treacle. Why do they do this?
The science bit!
For a full explanation see last week’s post.
We’d love to see your creepy or even very pretty density creations.

treacle is molasses
thanks! i was just about to google that!
Thanks, Donna! I assume corn syrup can sub for the golden, since that isn’t readily available in the states either. (My favorite granola recipe calls for Lyle’s and I’ve been wondering if it’s worth ordering…currently I sub honey.)
Oooh YUK!
