A 3.5-meter-diameter steel pipe unexpectedly rose over 10 meters from a sewer construction site in Osaka, Japan, baffling onlookers and causing significant traffic disruptions.Officials suggest draining water from the pipe, used as a retaining structure, caused it to float upwards, scattering debris but causing no injuries.This event highlights ongoing infrastructure challenges in
Osaka, with efforts underway to lower the pipe and address the aging water and sewer systems, a task previously aided by an anonymous gold donation.
