These Crystal Tree Kits are a gorgeous activity to keep the kids busy! A great little experiment and then decoration too.  Suitable for kids 4 and over, the crystals grow in just hours.  These ever-popular kits are selling fast.
 
These kits consist of a sachet of crystal solution and a cardboard tree. The tree soaks up the liquid, then as it evaporates crystals are deposited all over the tree.
 
Leave it white for that winter wonderland look, or add coloured food dye drops to the tree tips before adding the crystal solution to create a coloured masterpiece!
