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!
