We've recently been playing with Soapy Sand (see my previous post) and while the children are loving it I couldn't help but wonder..... what would happen if......I mixed in cornflour?
I started with a few good handfuls of cornflour and then added soapy sand, handful at a time, mixing well each time until I had a consistency I was happy with. The children were fascinated with the process, making comments and poking it with curious fingers.
The resulting gloop behaves almost exactly like cornflour and water but the soapy sand has the advantage of really bulking it all out so that we ended up with a whole trayful of gloop that allowed at least four children to play quite happily at a time without complaints that anyone was hogging it.
It does dry out over time but it's easy to top it up with a bit of water and my children were fascinated by the changes and I was able to feed in lots of vocabulary (solid, aqueous, liquid, runny, hard)
They loved that they could mould it in their hands but that it turned to liquid as soon as they stopped moving it, and then it ran between their fingers and off their hands.
And I found it all quite therapeutic too and my hands are lovely and soft... instant exfoliating treatment:-)
