The best career choice anyone could ever make – aside from the richest astronaut to ever win the Super Bowl – is the designer of the kinetic art installations found in science centers that roll billiard balls along tracks, around loops, and through conveyors in a perpetual display of physics and mechanics. [Niklas Roy] isn’t quite at that level yet, but he has come up with a new twist on an old idea: a machine that literally sucks balls from a ball pit into transparent tubes, sending them whizzing around the installation space.
The installation consists of eighty meters of plastic tubing suspended in the staircase of Potocki Palace in Kraków. Electronically, the installation is extremely simple; a PIR sensor turns on a vacuum cleaner whenever someone is in the ball pit. This sucks balls up through a hose, around the space, and into a bin suspended over the pit. Pull a lever, and the balls stored in the bin are dispensed onto the person vacuuming up thousands of balls below.
