Observe Freaky 'Casimir Effect': Makes Plates Attract Via Quantum Vacuum Flux

"The Casimir effect is a small attractive force that acts between two close parallel uncharged conducting plates. It is due to quantum vacuum fluctuations of the electromagnetic field. The effect was predicted by the Dutch physicist Hendrick Casimir in 1948."

"The demonstration shows that traveling water waves carry momentum. Here is a container of liquid. It is ethyl alcohol with the dye flourescein so that the waves can be seen. Water works, too, but alcohol is better. Two parallel plates are suspended from clamps attached to a support. The container rests on a shaker, which is off right now. The shaker will be driven with noise in a band of frequencies from 10 to 20 Hz, and will excite surface waves. What happens to the plates?"
