What we did: In an ice cube tray, filled with water (just full enough that the squares did not overflow into each other), we added a few drops of food coloring to each section, stirring with a toothpick. We carefully placed the tray in the freezer, and that afternoon we simply popped out the ice cubes and placed them on a divided plate (to make it easier to grasp.)
As the ice cubes melted a little, they left colorful streaks on the paper.
At first Elijah was concerned to watch his fingers take on a new color, but after a while he decided it was “Pretty.” It does mostly wash off with soap and water. A good bath took care of the rest.
“Cold!”
That night, when David got him ready for his bath, he showed me Elijah’s belly, saying “What is this?!” It was streaked with color from where Elijah wiped his cold fingers off on his belly!
We decided to switch to crayons to finish the picture.
This would make a perfect summer craft, especially outside, when holding an ice cube would feel good and cooling, not chilling.
My friend Karen came up with the even better idea of freezing a toothpick (or popsicle stick) into the ice cubes so that the little artist could hold onto something not quite so cold and maybe not have quite as “colored” fingers!
