Dan is the nerd's nerd." Well, can't get any higher praise that that, I suppose. :) I have a couple of neodymium magnets and yes, they are much fun. Never played with magnetic fluid though.

    The "nerd's nerd" couldn't handle three measly hits? This has to be a "slashdotting" record. ;-)

    That explains the form errors trying to reply to this story.

    Umm, Michael? Could you keep your fscking magnets away from the fscking servers? Thanks.

    just wait until this hits the infomercials.. they'll probably have some sort of offer for "therapeutic gel" that you bathe in. just toss your favorite electrical appliance in, and voila!

    " . . . small tanks of magnetic fluid that allow you to wave magnets around near them to see what happens in museums a couple of years ago"



    Wow! Magnetic fluids that affect museums in the past? There must be some kind of temporal anomoly going on here!

    Anyone tried getting someone to drink some of this liquid and trying to catch them with a large magnet ;).

    Better: send them to the airport.

    P.S. That begs the question--what comes after strip & cavity search?

    And do we realy want to know?
