In many ways Hot Wheels were the perfect child's toy: elegantly designed, intelligently weighted for velocity on a plastic track, and inexpensively priced. Those are also the reasons they make such great adult playthings too -- especially if you've got a lot of time on your hands and a giant house and backyard you're willing to convert into a Hot Wheels racetrack that's just a giant Rube Goldberg machine.
The course that YouTuber and cool dad Mark Rober built for his latest video -- which I urge you to watch above, in full -- is filled with gravity-defying stunts, explosions, and his son's toys. He created it by piecing together yards and yards of racetrack around his house, down the stairs, into his backyard, through his pool, through a basketball net, and eventually down the piping of his sink. He also added the Hot Wheels he had into the mix -- tiny die-cast replicas of Scooby-Doo's Mystery Machine, KITT from Knight Rider, the Delorean from Back to the Future, the Ecto-1 station wagon from Ghostbusters, and GMC van from the A-Team -- and did the only thing that made sense. He raced them.
