 Two thin glass panes are squeezed together with a rubber band but separated on a single side by a paper. This paper clip spaces the glass panes so they are only touching on the opposide side. In the area that the two glass panes touch blue liquid from a pool underneath the panes is allowed to travel up and in-between the glass to the top of both panes. The liquid can travel up where the glass touches due to capillary action. IntroductionHow do trees suck water all the way up to their leaves? How do paper towels soak up a spill? Are these things related? Try this project to learn about capillary action, and repeat a classic demonstration from over 100 years ago! CreditsBen Finio, PhD, Science Buddies
