Ice cube colour mixing
Tuesday, November 7th, 2006This is a short and sweet idea great for little kids who are learning the basics of colour theory. It was inspired by a suggestion made months ago by Kiddley reader Suz.
Pour some water into an ice-cube tray and then add a couple of drops of food colouring to each cube.

Freeze the ice cubes until they are solid. You will notice that once you have done this the colour will freeze around the centre of the cube.
When your kids need a little distracting (we did this one night at the dinner table when dinner was a little slow in coming) place two of the cubes in a glass of warm water. Place the glass on a piece of white paper in the centre of the table.

Your kids will have fun theorising what colour will be made as the cubes melt and mix.
