Homemade Antigravity?

Posted by Anita in Science & Tech, Video Clips on March 27, 2007 at 12:51 am


The guy in this video claims to have created a homemade device that levitates a card using only a Nokia cordless phone, batteries, a coke can, and a CD. Hit play or go to Link [YouTube]

Skeptical? Me too … although I couldn’t see any concrete evidence that it was staged. There’s even a video response that replicates the same experiment.

    THAT NOT LEVITATION!

    i agree. it's magnetism, if not a hoax.

    MAGNETISM QUALIFY AS LEVITATION!

    Fake! its done with a couple strands of hair or threads or in the case of the video response fishing line wich can be clearly seen in the upper left corner of the screen.

    The batteries aren't part of a completed circuit, the cell phone doesn't radiate energy in a frequency that anything there could harness, and the dime on the playing card has no ferromagnetic material in it.

    Can't be magnetic, can't be electronic. Must be bulls*

    Another video response, but this one suggests even *greater* power...

    The fact that he uses batteries is a decoy: batteries typically do not possess an electric field that extends that far out into air.

    Even if they did, they couldn't interact with a nickel (non magnetic, no charge).

    The big secret to this trick is the utilization of a magician's tool known as invisible thread. The thread forms a loop between the coke can and the CD stack, so that when he drags the coke can, the thread lifts and straightens out. This carries the card upward. The coin serves to keep the center of gravity of the card between the two sides of the loop.

    "free enegry" in an experiment involving no less than 5 batteries.

    It looks more like the card in the original has been added using a raytracer.

    I guess it is quite unlikely that the card sets back on top of the standing batteries in a perfect balance again, as if it had not moved...

    I knew all you smart readers would prove how gullible I am. Anyone have a bridge they want to sell ;)

    Bridge? I have one that's suspended by a mysterious force that doesn't fit our current model of the universe. I'm open to offers...

    James provides a good explanation. Batteries in and of themselves do not contain or generate electrical current until they're part of a complete circuit: positive to negative (or vice versa). There is no circuit in that video.

    I didn't know nickles (dimes, etc) were not magnetic (ferrous?). In any case, I'm not surprised its BS. Incidentally, where it might be true that 'MAGNETISM QUALIFY(sic) AS LEVITATION!', it's not 'Anti-Gravity'.

    Hoax.

    Try taping a dime to a playing card and see how hard it would be to balance it atop two AA batteries without it falling off.

    It is a trick:
    The card is supported by two parallel thin threads joined (for example) from the wall to the pepsi, like as a suspended bridge.
    The card is not joined to the threads, but simply supported.
    Initially the two threads lie on the cd-rom near the two vertical batteries.
    Moving the pepsi you can stretch the threads and so raise up the card.
    You can control the movements of the card with the tension of the threads by moving and rotating the pepsi.
    (rotating the pepsi you control the inclination of the card, by stretching differently the two threads)

    Tried it. Its all some bull s#!t
