Quick EYFS activity: Cornflour slime

Slime that is actually educational! This quick and easy activity requires only 2 ingredients (Water and cornflour!) has lots of learning outcomes, is straightforward to clean up and will keep enquiring small minds occupied and engaged.

Start with a bowl and a small amount of cornflower and let the children add a little bit of water to it and give it a stir, then add some more cornflour. Part of the fun is seeing the different textures and consistencies that occur as they add different amounts of water. Once you have a consistency you're happy with encourage the children to really get in and get their hands dirty!

Try rolling the slime into a ball, when you stop pressing it will seem to melt away! How about laying it out onto a flat surface and pushing it, can you see the water moving away from the cornflour as you press? Look at it while it's in the bowl, it looks wet like a liquid, right? slap the surface and it will feel like a solid. MAGIC!

This is a liquid that acts as a solid, it is a non-Newtonian fluid see here for the science!

Put the slime in a plastic bag and see how it feels, what happens when you drop it? The slime can be kept in a plastic bag for a couple of days. This is easy to clear up but don’t put it down the sink, it will block it! Just put it in a bag and dispose of it in a bin.
