I’ve heard that air bubbles in water can make it less supportive for floating. Why is this such a big deal?
Air reduces water’s density. If you fall into heavily aerated water, you can sink because the upward buoyant force is weaker.
It’s a big problem in places like aeration tanks for water treatment. Without proper precautions, people can drown quickly.
Aerated water is rare outside industrial or natural phenomena, but when it happens, it’s critical to avoid those areas.
