Look Mummy, I made a rainbow!

Penguin and Little Missy were busy having lots of fun watering the plants at Granny and Gramps’ house and playing with the sprinkler.

A little Later Little Missy was watering the grass and she calls out “Look Mummy, I’ve made a Rainbow.” And indeed she had made a rainbow; and it was beautiful.

It reminded me of and experiment we had bookmarked in a library book nearly a year ago. Sadly we never did the experiment and the book (having been renewed a few times) finally went back to the library. The book, Backyard Science by Chris Maynard explained how to make a rainbow and the science behind what happened when a rainbow is made.

To make a rainbow you basically need just two things, a lovely sunny day and a water sprinkler. Stand with your back to the sun and hold the sprinkler up in front of you. A rainbow will appear. How wonderful!

Sunlight is made up of different colours that we don’t normally see. Red, Orange, Yellow, Green, Blue, Indigo and Violet. Usually we just see sunlight as white light. Sunlight hits the waterdrops and the different colours seperate and we can see them in the form of a rainbow.

Have fun making rainbows 🙂
