Pupils from 8S who have finished their scholarships were on hand to help the year 2s make bicarbonate and acid rockets.
You can do this at home with baking powder and vinegar. Dilute acid does not stink as much though!
This was a borroca tube rocket powered by a chemical reaction.
They didn't go very high so we went on to investigate water rockets, launched by air pressure. Physics in action here.
Brilliant photography by Mrs Clabby caught this rocket mid flight.
The groups then made air powered rockets out of paper.
Some where very well decoratedFor the grand finale the children saw how to set up and launch a methane rocket. This was the most spectacular of the chemical reactions of the afternoon. Fortunately our in-house photographer caught the sheet of flame as the rocket took off as can be seen below.
