Cavitation

The video explains how propellers create cavitation, a process where low pressure causes water to vaporize into bubbles. These bubbles can collapse, releasing energy that damages propellers. Cavitation affects not only propellers but also marine life, such as dolphins, which have a speed limit due to cavitation. Some sea creatures, like the pistol shrimp, use cavitation to their advantage by creating shockwaves to stun prey.
