I know people will call me nuts, but this looks like fun: via The Daily Mail, we learn that an extreme sports enthusiast took a high-speed ride on a rollercoaster -- on specially designed roller skates!
An adrenaline junkie has taken in-line skating to new heights and set a new world record after racing down a roller coaster at speeds of 56mph.
Dirk Auer decided to go where no sane man or woman had gone before and skated down an 860 metre track in just over a minute.
Wearing specially designed in-line skates, the German made the attempt on the Mammoth roller coaster at the Trips Drill theme park in Stuttgart.
There's several photos accompanying the feat, including this one:
From a physics point of view, this is sort of interesting. On the one hand, it's probably easier to skate a coaster than it looks, because the banked turns of the coaster are designed to keep the forces a rider experiences pointing down into the track, meaning that one would expect that forces tugging from side to side are not too bad. On the other hand, I get the impression that Auer was traversing the coaster faster than a normal car would, which means that the banked turns would not compensate as well for his motion.
I predict that I won't have to wait too long to try such a thing: I'm guessing some enterprising theme park manager will design a ride similar to Auer's feat, though probably not one going quite so fast...
