Bottomless Pits: The Possibilities Are Also Endless


So I was watching a video that was made from the top of the Burj Dubai: the tallest building in the world at 2,684 ft. In the comment section someone asked if someone took a dump off of the top of the building, how long it would take to hit the bottom. Sounded like a pretty good question to me. So I started looking around for the the terminal velocity of poop. I ended up finding this thread on Reddit in which someone asks "If you were falling down a bottomless, but didn't realize it was bottomless, how long would it be before you stopped freaking out?" Almost immediately the conversation starts asking the really tough questions, and makes it way back to poo.

If while falling, you reached terminal velocity, and you pooped, would your poop float beside you forever?

    Reddit.com: We ask the tough questions.

      It's this kind of "gotcha" journalism that is killing Reddit.

    I wondered that too!!! And then I wondered how it would be if you happened to have a bunch of food falling beside you at terminal velocity, and it was within your reach. You could survive a long time, but there would eventually be poop encompassing your entire general area!

      i love you, so so much. i spent a delightfully long time vividly envisioning a perpetual fall in the company of only food and my own waste.

Oh, and the average weight of a bowel movement is about .27lbs (depends on weight of individual amongst other things). So if we say it's a .27lb dump, and exclude air resistance we can calculate that it would take approximately 12.9 seconds to hit the bottom. But it would exceed terminal velocity at some point so we can assume then that it might take longer, like about 15 seconds. The math is not exact, and is only an approximation.
