    Granted that astronomers win the “beauty contest” with the images they can display, but the solid state crew have the edge in that they can do designed interventionist experiments whereas astrophyicists merely observe. A demo of superfluidity, or a superconducting magnet levitating using only liquid nitrogen coolant (which is now commonplace in schools) is pretty impressive, rather than merely pretty. And the first time anybody sees a laser beam, after a childhood playing with torches, is always amazing. Which brings holograms to mind….

    I guess that the moral opposite of waiving your fee is waving it. This is like razing/raising a building: clear on paper but ambiguous in the spoken word.

      Indeed. We have a superconducting magnet demo we use on open days here. I’ve seen in umpteen times and still find it fascinating. A bit difficult to make it sufficiently portable to do in a pub though!

      One of the tragedies of recent years is that the Health and Safety Mafia have made it very difficult for schoolchildren to do real experiments for themselves. It’s one think to watch a demonstration, but quite another to do it yourself.

    It’s a very portable demo provided you have a decent thermos flask.

    Health And Safety have surely taken the fun out of chemistry more than physics.
