"It sounds like a conjuring trick. You shine a light into a gas, and the light gets swallowed. Then you pump the gas into another container, say the magic words, and the light comes out again."

i have always been a fan of science and this is just great.
basically cool matter to such an extent that it becomes 'undifferentiated'.
shine light at at in such a way that the cool matter 'records' the light.
A WHILE LATER UNDER CERTAIN CONDITIONS
warm the cold matter with a laser and the initial beam pops out again.

no use but great fun at parties [in a h2g2 kina way]

Interesting.

Anyone wishing to see the effect in action, don't bother watching the videos on that site as it doesn't show it. :roll:
