On Wednesday, we had great fun outside making a volcano on the playground. All you need is a bottle of cola and some mentos…and your running shoes on so that you can escape the volcanic explosion. Why not Google it or try it yourself.
We also made lava lamps using oil, food colouring, vinegar and bicarbonate of soda. There were fantastic discussions about what was happening and predictions about what might happen if we shook the bottle or added different colours.
Everything you need is listed on the following website – http://smallscience.club/experiments/lava-lamp/ if you want to have a go.
