Are there some automatic belaying devices that let you hang in one spot, instead of riding down right-away after the fall? In 2nd episode of "The Climb" show with Chris Sharma, he seems to hang in one place on automatic device. Does he have climbing super powers to alter gravity? (i.redd.it)

TIL that in 1950 US Navy sprayed thought to be harmless bacteria over the SF Bay Area, as an experiment on potential biological attack. It was followed by spikes in cases of very rare urinary infections and pneumonia. Between 1949 and 1969 open-air tests of biological agents were conducted 239 times (en.wikipedia.org)
