Product Description |
| Multi-coloured neon sand that never gets wet - even under water!
Add it to water - it never gets wet! Each tin contains 30g of Orange, Blue, Green and Purple coloured sand, each in a separate bag. This sand has been treated with silicon vapour , giving it non-polar properties, so it cannot bond with water and can never get wet. Non-toxic and completely harmless.
Includes 30g bags of Blue, Green, Orange and Purple hydrophobic sand. Full instructions for use and information on Hydrophobic sand from the Science Museum. |
