Jelle Bakker, better known online as Jelle's Marble Runs, is a Dutch YouTuber who primarily uploads videos about marble runs and competitions.
His channel is completely dedicated to marble runs. He is mostly known for uploading the Big Marble Run Machine with 11000 marbles, with that video gaining a total of at least 12 million views. That was his second most popular video. He made various series with marbles, such as marble runs, marble machines, marble rollercoasters, marble races, rolling ball sculptures, and more. He also made some original content with marbles, such as Marble League, formerly the MarbleLympics, which is basically the Olympics but the spectators and the contestants are all marbles instead of humans. In addition, the events are somewhat different so that they are more appropriate to marbles.
