What you need:
- honey
- maple syrup
- milk
- dishwashing liquid
- water (with food dye added, optional)
- oil
- methylated spirits
- a tall jar or glass
What to do:
- Pour some honey into the bottom of the jar or glass.
- Tipping the glass to the side, slowly add the other liquids in the following order: maple syrup, milk, dishwashing liquid, water, oil, methylated spirits. If you don’t have all of these, you can leave layers out, you will just end up with less layers at the end.
What happens:
You are able to get different layers due to density. Density can be thought of as how heavy something is, and it is caused by how tightly their molecules are packed together. Heavier liquids, like honey, will sit underneath lighter liquids, like maple syrup or water. You might find that some of the layers show a bit of mixing, especially if you don’t pour them in really slowly, but you will still be able to tell the difference between the different liquids.
