We're at the cottage again and today we did a very simple, very cool science experiment.
I followed the instructions from this website: http://coolscienceexperimentshq.com/color-changing-water/
...which has many excellent science experiment ideas!
Supplies: glass bowl, tall glass, food colouring
To set up the experiment, Monkey filled the glass and the glass bowl with water.
Next, he dropped in the food colouring. The water in the tall glass was coloured blue, and the water in the bowl was coloured yellow.
Now for the best part! Monkey (carefully) picked up the tall glass and placed it inside the bowl. The result is amazing!
The water in the bottom of the tall glass appears to be green! It looked so cool.
I was really impressed by how perfectly this worked.
Once we had looked at it for a little but, Monkey wanted to pour the blue water into the bowl.
Even more green!
We did try this with yellow water in the bowl and red water in the tall glass, too. Peanut even got his hands in there this time!
It didn't work nearly as well. Basically it didn't work at all. I'm not too sure why... Perhaps the contrast between the red and the orange wasn't enough? Monkey wasn't too upset about it, especially after he got to pour the red right into the yellow.
We didn't bother trying to make purple, partly because I was discouraged after the orange didn't work but mostly because we ran out of blue food colouring. So, if you do this, I would recommend only making green! It works really well and you won't be wasting food colouring or water.
