Playing With our Food

Later, after a chance comment regarding the rumoured powers of cornstarch, a visit to Tesco was called for. We stocked up on cornflour, hoping it was the same thing, then proceeded to make one hell of a mess all over my kitchen…

Cornflour Experiment

The instructions in Penn and Teller’s How to Play With Your Food were to add a little water and ‘just play’. So we did. It’s such cool stuff! If you push your finger slowly the mixture sloshes like water, but if you scoop up a load it globs and you can roll it around. Once you stop it immediately ‘melts’ back into liquid and flows away. The harder you push, the more resistance there is – it even cracks if you punch it!

The Cornflour Mess

It’s more fun than is legal in some countries. It also lends itself to incredibly filthy comments, but we didn’t make any of those; oh no. We messed about for ages, getting mixture everywhere. After a while it becomes a little too solid, but a touch more water fixes that. We added food colouring, which worked surprisingly well…

Dyed Cornflour

…and managed to avoid the temptation to start a cornflour-fight. We eventually killed it by adding washing-up liquid. As Tamsin pointed out, we should have realised that wouldn’t work – washing-up liquid is designed to get molecules to separate, after all.

I highly recommend you have a go 🙂 One caveat, though: it’s a complete git to clear up. I’ve wiped down the surfaces twice now and the damn stuff keeps coming back.
