Sure, you may have had some Hot Wheels and a Hot Wheels race track when you were a kid, but you've never seen a Hot Wheels course like this before. Built out with eight different track sections connected via teleporting tunnels, this track goes from their backyard, up and down a hill, towards the pool and back again. The geniuses behind this badass Hot Wheels contraption explained exactly how it worked on their YouTube page. "Each section worked on its own from tunnel to tunnel. The cart is powered entirely by gravity at all times. In total there are 11 cuts in the video, 7 between locations and 4 for slow motion footage. The jump section and the loop section were filmed twice, once in 30 fps and again in 120 fps, and the final video cuts from the normal speed footage to the slow motion footage for the duration of both the jump and the loop." Perhaps the most impressive part of this entire 200-foot track is the fact that it goes underwater. "The cart worked reasonably well underwater and only fell off the pool track a few times. The main problem with the pool track was keeping the track connected and in place. A rock was attached to the end of the track in order to weigh it down." The entire journey was filmed on a GoPro, and you can watch it in its entirety below.
