I thought that a lemon made electricity because it was sour.
I experimented on an orange, a kiwi fruit and an apple.Two worked, the orange and the kiwi fruit but only for one second.We said peel at first from the ones that worked but we were wrong.
Next we said sour and we got it but what made things sour?
It was tartaric acid. We had lots of fun.
