A stubbornly persistent illusion, 2016

steel, dc motor, belt and pulleys , beechwood, white oak, hourglass, leds, plastic

100x30x50 cm


An hourglass is brought to its halfway point, until there is the same amount of sand on both ends.

It is then spun fast enough so that centrifugal forces stick the sand on both ends of the hourglass.

A strobe light is then synchronised with the speed of rotation giving the illusion of a static hourglass in which sands doesn’t flow.
