Hands-on: Raincloud in a Jar

The other day we carried out an experiment in the laboratory. We learnt that when clouds get so full of water that they can’t hold any more, the water falls back to the ground as rain. Steps:
1- Fill a jar about 3/4 full with tap water.
2- Use the shaving foam to create a cloud on top of the water.
3- Let the foam settle a bit.
4- Now drop some food colouring into the ‘cloud’. As it fills up, the food colouring will fall down into the water creating a rain-like effect.
