"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]
