Berthil van Beek is a LEGO enthusiast that converted the Akiyuki Marble Run into a stand alone Great Ball Contraption made entirely from LEGO pieces. If none of that makes any sense—don’t worry, we’re with you—it’s basically an incredibly complicated perpetual motion machine that rockets LEGO soccer balls and basketballs through a winding roller coaster or tracks and accelerators at 1,000 RPMs. They call these ridiculous inventions “Great Ball Contraptions,” and this one is absolutely mesmerizing. We can’t even imagine the amount of time and effort that went in to creating this, but we’re happy that it’s finally finished so we can watch it on repeat in complete awe.

 You can’t have a fall evening without a fire. And you can’t have a fire without a Cowboy Cauldron. They’re built from solid plate steel, meaning they’ll last a lifetime or two and they come in four different sizes with elevated basins that can be adjusted to any height. We’re going with The Urbaan Cowboy® because it’s perfect for entertaining at home.  With a 30″ diameter basin, it is more than large enough to have a nice fire, but still small enough to pack into a pickup truck and take it with you.  Can you imagine the envy when we bust this puppy out at a tailgate or the beach? We haven’t seen a more handsome fire. You?  Best of all, Cool Material readers get an exclusive deal.
