Colour theory

Perhaps inspired by our egg-colouring activity over the weekend, Dex has been into playing with coloured water big time. This morning at the breakfast table, he put in a request for "another glass" and when that was delivered was followed by a request for "another glass - the big one."

So in front of him this morning was his little juice glass, plus a little bigger regular sized glass and another short, wide mouth glass. All he wanted to do was practice pouring his juice from one different-sized vessel to the other. I convinced him to drink his juice instead of playing with it but on the promise of replacing the fluid -- some splashing was happening and I dreaded the clean up. Instead I filled one glass with water and when the protest started, I brought out the food colouring and put in a couple of drops of yellow. That got his attention.

"I want green," he said. So we talked about what would turn yellow to green and we decided we should add some blue. A drop of blue into the yellow and he was thrilled with the result! He started drinking green water and began his fluid transfer from one vessel to the other. That was our art and science activity this morning.

I hope food colouring is really not that harmful because I have a feeling drinking coloured water is going to be part of our regular ritual from now on.
