Answer 1

Water is more dense than air. If you add bubbles, then there’s less water and more air per volume area. This makes the volume area less dense. Higher density things sink, so things that were less dense than water and floated (e.g. boats) are now more dense than the aerated water. These things then go blub blub blub (they sink).
