INCREDIBLE as it may seem, the iconic lava lamp is more than 40 years old.

It was patented by Singapore-based inventor Edward Walker in 1965 and manufactured at a factory in Poole, Dorset.

Sales took off when a US businessman snapped up the US distribution rights and christened the light a lava lamp.

The lights quickly became popular with the peace movement of the Sixties and have remained popular ever since. They even survived a safety scare in the Eighties, when someone heated his lamp on a stove to speed up the melting process - and it exploded in his face.

Now you can recreate that funky feel - albeit on a smaller scale - with the lava lamp phone charm.

Attach one to your phone and the bubbles flash red when a call comes through. What a great mobile phone accessory for a mere £3.95.
