Precipitation

We used:Shaving cream, food colouring, water and a jar to find out about precipitation. First put the jar on a table. We poured water in a jar. Next we sprayed in the shaving cream. Around the top of the jar. Then we dropped in the food colouring. Keep on doing that until it starts to fall in.
How it works: I think the shaving cream was not too strong to hold in the food colouring water and it falls in when it is heavy.
