Mrs Shewring demonstrated how to make a dancing raisins experiment. We mixed baking soda and vinegar together in water and the mixture began to make lots of bubbles. There were raisins in the glass and they were carried up to the surface of the water. Then the bubbles popped and the raisins dropped down again where there were still more bubbles. That's how the raisins were going up and down and looking like they were dancing!
