Magic Growing Xmas Tree
Dress your Magic Christmas Tree with a star and Garland for extra Christmas Cheer!
How does it work?
The saturated solution of crystals and H2O are drawn up the tree (which is made out of absorbent blotting paper) by capillary action, and also by the force of gravity on the surface of the liquid in the dish.
The increased surface area at the extremities of the tree results in a greater evaporation rate of the solvent (H2O). The solute (crystals) are left behind on the surface of the blotting paper. There are special non-toxic dyes in the tips of the tree that are soluble in water. As the saturated solution moves upwards and outwards, the dyes are carried along to form the colours as the crystals grow, creating a fantastic effect.
A fun kids science experiment, this novelty toy is a fun Christmas Gift.
