"We've learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other." British scientist Robert Boyle discovered the use of litmus paper over 300 years ago.

It's hard to get a clear result. Will there be a better indicator than litmus paper? The three kids decided to try and find out! How? They went to collect over 40 plants in parks, gardens and markets. Then they ground leaves, flowers and stems to get the pigments from them. The kids mixed pigments with acid and base. They spent months watching carefully to see which paper showed the best colour change. They decided it was the litmus paper!
