'more time on your hands than you know what to do with', department,
but I have to say quite fascinating, it is the science of creating hurricane balls, take two round objects of roughly the same mass, glue them together using something like hot glue and spin them on a concave surface like a bathroom mirror, and then use a straw or a blower to blow air on one side of them, it is said that they can spin at up to speeds of 12,000 revolutions per minute!
the science of it, according to Make, was explained by the
19th century French mathematician Louis Poinsot, he was the first to
demonstrate that any number of individual forces pushing or pulling on a rigid
thing can be simplified into just a single linear force and a twisting force
called a couple, so take all the force from blowing on it, combined with its
already existing spinning momentum, and we get a little hurricane going incredibly
fast in no direction at all, absolutely amazing!
in a new video from PBS
Digital Studios, homemade special effects guru Joey Shanks shows off the
fascinating, simple joy of making and spinning hurricane balls, in the video he demonstrates the use of strobe and ultra violet lighting amongst other effects, all of this from having too much time on your hands!
