Final answer:
The active victim front rescue is a technique where the rescuer stays afloat with a rescue tube between themselves and the victim, similar to how a needle can float on water due to buoyancy and surface tension.
Step-by-step explanation:
The active victim front rescue allows you to remain on the surface of the water, with your rescue tube between you and the guest. This technique is a fundamental water rescue skill often taught to lifeguards and those involved in water safety. The positioning of the rescue tube aids in keeping both the rescuer and the victim afloat while ensuring a safe barrier is maintained between them. It is analogous to how a needle on top of a glass of water or for a water strider to stay afloat on the surface layer of the water, relying on the principles of buoyancy and surface tension.
