A Former NASA Engineer Builds The World's Longest Hot Wheels Track!

Former NASA engineer and entertaining science vlogger Mark Rober decided to take on the challenge of building the World’s Longest Hot Wheels Track inside of his massive warehouse. Apparently, he’s been wanting to accomplish this feat for a long time and he finally pulled the trigger on making it happen!

The track runs more than a half-mile long, and while it does beat the current Guinness World Record of just under a half-mile, this track has yet to be officially crowned the longest. The video came with the following note:

Since I was like eight years old I’ve had this dream to design and build my own warehouse and this is it. Welcome to Crunch labs …if you look right here we’ve got the start and finish line of the world’s longest Hot Wheels track at over a half a mile.

You can watch Mark show off the Hot Wheels track in the video below!
