When a Hot Wheels track starts from the roof of a house, you know it's going to be good. This isn't the first high-riding die-cast course we've seen from Backyard Racing on YouTube, but at nearly four minutes for a single lap, it's the longest. It's also the most complex, featuring multiple powered lifts and a series of waterslides to enjoy on the way down.
The track is appropriately called the Hot Wheel Aquapark Track, and it indeed begins on the roof of a house. A massive suspension bridge carries the camera car deep into the yard, where a literal tower of track awaits. According to the video description, this particular track utilizes multiple ladders, lots of wood, clear tubes, popsicle sticks, Jenga blocks, zip ties, rain gutters, and more. You can probably guess what the gutters are for.
