in 2010, a camp counselor goon logged on to the somethingawful forums asking for help with the zipline he build from scratch, and with no engineering knowledge, that didn’t seem to be working right. when he tested it with a sandbag, it continued to gather speed during the entirety of the 143 foot drop (19 degree slope) until it slammed into the wooden platform at the bottom at a speed of 65mph, presumably creating a child paste that would have to be scraped off to be sent home. there were pictures.
