As I want to take a new approach on rain and alter people perspective of rain, I researched ways of recording rain. I decided to make Ph indicator paper which changed colour when acid or alkali is present, and from doing research I discovered that rain will show up on this paper and alter the colour.
(never realised how interesting the inside of a red cabbage is)
I soaked the paper for a couple of hours then left it to dry.
It works!
I tested the paper fully worked by using something very acidic, a lemon, and sure enough the paper changed colour to a very bright pink. I also tested alkali by using a small amount of bleach just to see what colour the paper went, it turned green.
