Ski Jumping has always fascinated me, though I couldn't tell you why. I have no plans to go airborn with long sticks on my feet.
Here's an interesting take on using a ski jump in the summer: instead of skiers, let's toss tires down the ramp and see how far they go.
The Japanese commentary only adds to the humor. It appears that this is some sort of Japanese TV show, along the lines of "I wonder what would happen if we tried this?":
Here's another episode with a giant rubber band. Who hasn't thought about trying this?
And this episode involves shooting kleenex with a handgun. Apparently, it takes 2354 sheets of kleenex to stop what looks like a 9mm bullet. It makes me laugh!
