The mystical Magic Garden starts to grow within hours of being planted. Set up the cardboard trees and mountain on the tray provided, add your solution and sit back and watch! As the liquid moves up through the paper and evaporates, crystals will magically begin to appear.
How Does It Work?
The Magic Garden is an example of the physical phenomenon of capillary action, or capillarity. It is the ability of a liquid to flow in narrow spaces without the assistance of, and in opposition to external forces like gravity. It occurs for several reasons, namely cohesion (the tendency of molecules of a substance to stick together - water is very cohesive which is why it sticks together in puddles) and adhesion (the tendency of some substances to be drawn to unlike substances - which is how a tree draws liquid up to its top branches).
Did You Know...?
Albert Einstein's first paper, submitted in 1900, was on capillarity.
