I’ve heard about water that’s less buoyant due to air or gas bubbles. Could this actually be dangerous?
Yes, it can be. Aerated water, like in wastewater treatment tanks, has reduced density and buoyancy, which makes floating difficult. People have drowned in such conditions.
It’s not really ‘non-buoyant’ water; it’s just less buoyant. But in large-scale cases, like gas released from seabeds, ships could lose stability and sink.
This is rare but possible. Industrial tanks with air-infused water are the main culprits. Safety measures are key in those environments.
