My 3½ year old son is into magic at the moment and wants a (working) wand for his birthday! In our ‘boredom busters‘ post one of my readers, Jo, came up with the fabulous idea of making magic potions – naturally I thought my son would love it.
So here’s the lowdown on magic potion #1: Get a handful of red cabbage, chop it up and pour boiling water over it to produce a blue dye.
Get some lemon juice and add a few drops to the cabbage juice.
Watch it turn the most AMAZING pink! (I have not enhanced the colours in these pictures at all).
Here’s the science: Red cabbage juice contains a natural pH indicator that changes colours according to the acidity of the solution. Read more about it in this great article at chemistry.about.com.
Anyway, it’s a really cool little experiment and my son wants to do it every day at the moment. We’ve already waded through a whole cabbage in the name of scientific research. I still can’t get him to eat any though! Incidentally cabbage juice makes the most amazing pink playdough!
I’m going to do a whole series of posts on magic potions so keep your eyes peeled.
I’ve also got some valentine craft coming up in the next few days. I’ll get the boredom busters page up by the end of the week – it’s taking a little while to put together, simply down to the amount of brilliant suggestions I’ve had.
