Firstly we put some newspaper on the tables. Each group got a plate and a plastic cup. We put the cup in the middle of the plate and we put flour around the cup so that it looked like a volcano. We put 3 spoons of bread soda into the plastic cup. We also put in a drop of food colouring to change the colour and we put in some washing-up liquid to speed up the reaction and to make more bubbles. Lastly Ms Druhan measured out 50ml of vinegar. We poured the vinegar in to the volcano and we waited. The volcano erupted and the lava flowed down the mountain. It was exciting.
