Why A Chain Falling Out Of A Cup Appears To Defy Gravity

chain-defying-gravity.jpg

This is a video explaining why a chain falling out of a cup appears to defy gravity briefly before spilling to the ground. Basically the chain gathers so much upward momentum while leaving the cup that it can't change direction immediately, and has to do so in an arc rising from the cup. Does that make sense? I'm trying my best to explain it but I did get fired from teaching science for telling my students that air and rock are chemical elements.

Hit the jump for a video of the chain falling, then a longer, explanatory video.

Thanks to to fat piggie and Alan, who agree it would have looked even cooler if they'd used some of the chains like Mr. T used to wear.

    it would be really interesting to feed (mechanically) the chain back into the bottom. Make this thing look like a never ending stream.

    Science! That's why it's on a beaker.
