Strange instrument's marble melody captivating the internet

It's called a Wintergatan - a musical instrument built using 2000 marbles, and its melody is captivating the internet!

It was built by Swedish musician Martin Molin, who created a wooden music box powered by marbles.

How did he do it? Pulleys, levers, and gears.

The user turns a crank that moves 2,000 marbles around on tracks and through funnels.

The marbles then travel around and come in contact with other instruments like a kick drum, a bass guitar, and a marimba.
