Hi,
I have done one of your experiments with a friend of mine, the one about blue sky ('now you can explain why the sky is blue and the sunset is red') and it went very well. We only have one question about it, we didn't understand why you have to use powdered milk to get the results. So if there is any particular reason for that, I would appreciate it if you'll email the answer to me as soon as possible.
Thank you.
