The campus at The University of Regina is a large collection of buildings constructed around a central ellipse and all connected (presumably so that people can get from building-to-building without having to go outside and freezing to death in the winter). One result of this design is that there are some very long corridors.
The longest hallway, by far, is on the south edge of the central campus running past the phys ed dept, the gyms, and all the way to a pit that has vending machines and ping-pong tables. When I first saw that corridor thirteen years ago, I had an inexplicably intense desire to stand at one end and try to see if I could throw or roll a ball to the other end.
Alas, I didn't do it, and now there's enough lounge furniture in the way that I'm not sure anyone could get the ball through the morass.
However, there are other corridors. The one in the photo below runs from the east end of the ad-hum (admin-humanities) building past the library and down to the east wall of the classroom building.
There's a large-screen tv-type monitor that you might be able to make out at the far end of the hallway.
This year I didn't wait. I ordered some superballs from Amazon:
and took two of them with me to campus on Monday to try throwing them.
On the first two attempts, I tried throwing them overhand, but I was horrible and didn't get them past the doorway that you can see in the first photo (there's a reason I never made it as a pitcher in little league).
And so I collected the two balls and threw them underhanded (or rolled them with great speed? I'm not sure). Each of these two attempts barely missed the center post in the doorway and went the full distance. This is where they ended up [the shadow above them in the photo is the shadow of big-screen display unit]. I don't know if they actually hit that wall, but I'm guessing they did:
Looking back down the hallway, the east wall of the Ad-Hum building is way off (I figure about 2 miles*) in the distance.
The rolls had to be fairly straight to get through the initial doorway, and both attempts barely missed that centre post; but after that for all I know the balls bounced and caromed their way to the end. From what I could see, though (keep in mind it was nearly two miles*), both of them went right to the far wall.
Test completed! Success! Fun!
Now to organize a "Superball Long Hall" party with my friends!
*okay, okay, it wasn't really two miles. I'd be surprised if it was over 100 metres.
