Air bubbles rising from a scuba diver in water A soap bubble floating in the air. A bubble is a globule of a gas substance in a liquid. In the opposite case, a globule of a liquid in a gas, is called a drop. [1] Due to the Marangoni effect, bubbles may remain intact when they reach the surface of the immersive substance.

The animal snaps a specialized claw shut to create a cavitation bubble that generates acoustic pressures of up to 80 kPa at a distance of 4 cm from the claw. As it extends out from the claw, the bubble reaches speeds of 60 miles per hour (97 km/h) and releases a sound reaching 218 decibels. The pressure is strong enough to kill small fish.
Meanwhile, for Dr. Brandon, the most beautiful natural phenomenon is the northern lights, whereas the most fascinating is the diel vertical migration. "It's the largest migration on the planet ...
If the bubble is not long enough to encompass the object, especially at slower speeds, the bubble can be enlarged and extended by injecting high-pressure gas near the object's nose. [1] The very high speed required for supercavitation can be temporarily reached by underwater-fired projectiles and projectiles entering water.
The equipment intended for direct measurement of the explosion-generated underwater bubble was not operational at the time of the shot, but based on other measurements, the bubble's maximum radius was calculated as 376 feet (115 m), and its pulsation period approximately 2.83 seconds. [5]
