Place your rock on any printed surface and watch the tiny fibres transmit the image to the top of the rock. This unusual effect is the result of your rock's amazing fibre optic properties.

TV Rock is ulexite or hydrated sodium calcium borate hydroxide (obviously!). Ulexite results from the evaporation of water in intermittent lakes. When cut across the grain with flat polished faces, the rock gains the ability to project an image of the surface beneath it. 

Suitable for children aged 6 years and older
