Harrison and Alex love science, and are beginning to understand that if it is cloudy it sometimes means that it is going to rain. This was a really simple, but effective (and pretty!) ‘experiment’.
I filled up some clean empty jars about 2/3 full with water and squirted a big blob of shaving foam on to the top to cover the opening of the jar, and left it for a few minutes to settle. I then set out a few small containers of water coloured with liquid food colouring and a couple of plastic spoons. If you have eye droppers or pipettes it would work even better, and be great for fine motor control development. We haven’t got either but the spoons worked perfectly well.
We carefully dropped some of the coloured water into the shaving foam ‘clouds’ and watched the colour slowly spread through the foam. After a while, the coloured water began to drip through into the clear water (the ‘rain’), creating some lovely swirly patterns. We did this using other colours and the effect was beautiful! Eventually the water becomes so discoloured you can’t see the drops anymore but we were having so much fun we just did it again!
This was a great way of introducing a scientific concept to the boys. We talked about how the clouds were getting really heavy and fill of the coloured water and when they became too full, they needed to let some of the water out.
Now, when it rains we can look up at the clouds and remember that it is because they are full of water!
