Frankie, Hope, Sabahat and Kalie all agree that it was the best scientific experience they have had.
We learnt about physical and chemical changes and got the chance to mix different chemicals to see what happened.

Firstly they used sodium silicate, water, copper sulphate and magnesium. The reaction of chemicals with metal meant that they could grow crystals. It was a slow process but they could see their crystal garden start to develop...... but a much quicker reaction was when they mixed Mentos with diet coke!
The explosion with the mentos and diet coke was hilarious
