Saturday school in the Science Department is always something a little different! It is a great opportunity to see Science in everyday life. This week the Year 6 boys made bath bombs, complete with colouring and perfume. The combination of Sodium bicarbonate, magnesium sulphate (Epsom salts), cornflour and citric acid was mixed with oil and a small amount of water. They were then pressed into the moulds and left to dry out. Once the dried bath bombs are dropped into water the sodium bicarbonate will react with the water, causing it to release gas and make it fizz and dissolve! The boys had great fun measuring out the quantities and making the bath bombs; parents beware when they bring them home!
