The weird machine below is actually an instrument called the Wintergatan Marble Machine and is going to give you the most delightful musical experience.
Let's take a little taste of how the Wintergatan works:
Complicated, ha? This spectacular hand-cranked contraption was created by Swedish musician and inventor Martin Molin.
Believe it or not, it's comprised of over 3,000 internal parts and took 18 months to build. The instrument features 2,000 cascading steel marbles that operate a vibraphone, drums, cymbals, fretted strings and tuned percussion to make music.
And now, let's the music play mesmerizing sounds by Martin and the Wintergatan.
