It’s annoying when you get toys at Christmas but you haven’t got batteries for them… but what if Santa’s sleigh needed Rudolph’s bright red nose was running low on juice? Without that fog light showing the Jolly Saint Nick where to go there’s no toys for anyone.

But thankfully we all leave him snacks out overnight and our friend Father Christmas is a great electrochemist so he can make his own battery to recharge Rudolph’s nose!

You may have seen a lemon battery – with zinc and copper electrodes – but I bet you’ve never seen an entire Christmas dinner being used as a battery, have you?

We ended up with a solid 2 V out of this!

That’s all from X-Peri-Mas! It has been so much fun and I hope that you’ve enjoyed them too. If you try any of these experiments out please do share your results with me!
