The Atomic Lab. I have been reading Richard Feynman's QED (Quantum Electrodynamics) and it got me to thinking about the famous two-slit experiment. So I went looking on the web. I have not yet found what I was looking for (which was specific dimensions of the slits and the beam of light) but I did come across this website, which, among other things, has a pretty good explanation of what a Bose-Einstein Condensate is, and how it is made.
Never mind the picture, you can't buy it at the store, but who knows? In 20 years you might be able to. Lasers were invented 50 years ago and now they are everywhere. No, we don't have Ray-Guns yet, but that's probably a good thing.
Update February 2017 replaced missing picture.
Buy a BEC and you can run a stop-light ;-)
