Science Lab: Chromotography

Cutting strips for the chromotography experiment.
Hanging the strips on rubber bands so they just touch the bottom.
(My boys drew lines with a different colored washable marker on the end of each strip.)
Adding water in small amounts until it touches the bottom of the paper.

Capillary action at work, separating the colors!

Results in our handy-dandy lab books.
