One way to illustrate density is to pour liquids with different densities on top of each other. The liquids that are the most dense sink to the bottom.
I tried to make a summer ice cream version, but the sprinkles dissolved in the water, making it a bit murky looking.
Why does this work?
Each of the liquids has a different mass of molecules or different numbers of parts squashed into the same volume of liquid. This means they have different densities, and therefore one can sit on top of the other - the more dense a liquid is, the heavier it is.

Ice cream density! That's an awesome idea 🙂 Pinning it

Such a perfect demonstration! x

But what do I do with the density experiment after? Can I throw it down the sink?
