This one is definitely not my usual type of build. The Amazing Race is a very large rolling ball sculpture built for a Linstol trade show booth, and everything about the tracks has a specific purpose. The idea is to show how Linstol moves freight around the world faster and more efficiently.

The sculpture demonstrates this using two very different types of balls. The red balls are lightweight plastic, while the shiny metal balls are solid steel and very heavy. A chain lift spanning the entire 7-foot height of the sculpture carries both types to the top and releases them onto the same track.

That's where the race begins.

As the balls work their way down, they encounter a series of teeter-totters. The lightweight red ball rolls straight across without tipping them and continues along the fast route. When the heavy steel ball reaches the same teeter-totter, its weight tips the mechanism and sends it onto a completely different path.

The red ball represents Linstol. It gets the smooth, direct route from top to bottom—quick and efficient.

The steel ball represents the alternative. It gets dumped onto the slow route, filled with zig-zags, detours and deliberately slow sections. By the time it reaches the bottom, its journey takes about three times as long. A red ball can start at the top and make it all the way back to the lift before a steel ball that was already halfway down finishes its trip.

The ball separators represent the different stages freight encounters during its journey: Origin Port, Sea Freight, Destination Port, Rail, Warehouse, Overflow Warehouse, Caterer/DC and Plane. At each stage, the sculpture visually demonstrates the difference between taking the efficient route and getting sent on another time-consuming detour.

There's another detail built into the system. Every fourth ball is diverted to a separate chain lift and returned to the sculpture at the warehouse level. This represents the roughly 25% of freight being reinserted into the system at the warehouse and restarting its journey from that point.

I like this project because the rolling ball sculpture isn't just decoration for the booth. The tracks themselves tell the story. Weight, gravity, timing, track splitters and different routes turn a fairly complicated logistics idea into something you can understand just by standing there and watching two balls race.
