Test tube | Polymer snow
Create your own winter wonderland at any time of year in seconds with this test tube full of erupting polymer snow! Made of tiny white superabsorbent polymers - simply add water and this magic snow expands up to 100 times its size. The resulting snow is almost entirely made up of water, and as the water evaporates, it produces a cooling effect - so your snow looks and feels just like the real thing! Left for a few days, your snow won't melt, but will dry and be ready to expand again!
For extra fun try adding a few drops of food dye to the water before mixing for colourful snow. The perfect gift to delight young scientists while teachign them all about the properties of water, super absorbant polymers and endothermic / exothermic reactions.
