Hendrik Ball is a collector of unusual toys and his YouTube channel has thousands of subscribers who stay connected to see what he'll share next. In this video, he demonstrates how a toy he dubbed the "Zurich Mechanism" works.
It's an odd, dual-axle contraption that Ball says should rely on gears or a pulley to work. But it doesn't. You crank the handle and the axle on one side interacts with the axle on the other, making both sides rotate simultaneously. Curious.
