Introducing the “Marble Tsunami!”
Self-proclaimed “Marble Master” Jelle Bakker has built a giant machine in which over 11 thousand marbles are sent through a winding, jungle-themed maze for no reason whatsoever.
And it’s pretty amazing.
Warning: It’s also very loud, and it goes on like that for about 6 minutes. So make sure to turn your volume down ahead of time.
The whole this is about 33-feet long, 4-feet wide and 6-feet tall.
He started working on it back in April and expects to have it completely fine-tuned by sometime in June. This presumably will include adding some noise-dampening features.
