We tried this one once before and it didn’t work at all. Still not sure why! But Nova asked me one morning if we could “try the shaving cream colours again” so we tried again!
It turned out much better this time. Obviously adding colours over and over starts to make the water a gross colour, but Nova likes that for some reason!
This is a fun one though! It’s super easy for kids to do on their own and for them to see almost instant results as they add the food colouring and water! I can tell Nova really liked the independence of being able to do the experiment herself.
What to try it? http://onelittleproject.com/shaving-cream-rain-clouds/
First I set Nova up with water in four dishes and let her add the food colouring and mix up the colours.
