Sadhbh and Robyn demonstrated rain using shaving foam and food colouring. On top of some water, they sprayed shaving foam (to represent the clouds), they gently added a few drops of food colouring (to represent rain). When the cloud gets too heavy, the drops fall through as rain! When water droplets grow heavy in the sky, gravity pulls them down from the clouds as rain, just like in the experiment.
Its amazing
Excellent work Robyn and Sadhbh, I loved watching it. It was also really cool!
Your experiment was excellent!It worked out so well and the food coloring fell down like real rain!
