Observe Startle Response in Work Area Context

What happens here

The video opens with a view inside a van, which appears to be set up as a living or work space, indicated by the wooden ceiling, light fixtures, and various items like chairs and bags. A prominent red pole stands vertically in the foreground, near the entrance. An individual is seen stepping into the van. As they fully enter the space, an off-screen, sudden, loud noise causes them to visibly jump, recoil their upper body and head, and clutch their chest in surprise. After the initial shock, they realize it was a prank and begin to laugh, engaging in light-hearted banter with another person partially visible in the driver's seat. While this specific event is a prank and no overhead obstruction injury occurs, it vividly demonstrates the potential for sudden, uncontrolled movements in response to unexpected stimuli.

Goal: An individual enters a van and is startled by an unexpected loud noise, causing them to physically recoil and express surprise, before laughing it off as a prank.
