They did manage a good test to sink a boat, but the amount of bubbles they had to generate were phenominal.

Part of the waste water treatment process (posh name for sewage) is to pass the sh1tty water through aeration lanes which are concrete channels about 5m deep with perforated pipes in the bottom, similar to huge inverted shower heads. The pipes are fed by compressors which blow air through the water to aid microbial digestion. The lanes are heavily guarded to prevent anyone falling in, even lifebouys & lifejackets are useless, it's akin to trying to walk on air. The only way to work around them is either to switch off the air supply, which screws up the process, or to be fully harnessed & tethered.
