I wish I could credit the website I pinched this idea from, but I’ve searched and I can’t find it. No doubt it’s something I saw on Pinterest! Anyway, for something different, I painted a couple of plates with food colouring, covered it in bicarbonate of soda and gave the Wildthings a little bowl of white vinegar and a teaspoon each. This was one of those simple things that made them gasp and talk about magic- it’s a must, but very,very messy as you’ll see. Even Bob the Builder didn’t fare too well out of it, although I’m pleased to say it all came out in the wash!
