Ever since the days when I spent my days rolling Hot Wheels cars down the orange track and around the loop, I’ve wondered whether it would be possible to do with a real car; leave it to the guys at Top Gear to pull it off! (VideoSift link)

They seem to go through a lot of hullabaloo over the g-forces involved, but it seems to me that the 6-g’s would be only momentary, during the transition from horizontal to vertical, then again when it goes from vertical to horizontal; when it’s upside down there’d be nearly zero-g’s. Still something to be concerned about for the structural integrity of the loop, and the car’s suspension, but not so much for the driver. But no more concern than for the riders in a roller coaster.
And speaking of roller coasters, how about this; The Blue Streak — a home-built backyard roller coaster! Only one rider at a time, but it looks like it could be a real rush. The guy who built it did a great job of engineering the track; not overbuilt, but looks like it holds together pretty well. Too bad about the 200lb weight limit though. Time to lose a few lbs maybe!
Dude, that is so awesome. Coolest thing ever.
