What if a glass of water were LITERALLY half empty?

xkcd's What If?

This video has been trending in United Kingdom, Canada, United States, and Papua New Guinea

In the intriguing video 'What if a glass of water were LITERALLY half empty?' we are presented with a tantalizing scenario that delves into the physical dynamics and repercussions of a glass of water suddenly becoming half empty, but with a twist.

The script explores the traditional concept of a glass being half full or half empty, highlighting the perspectives of both optimists and pessimists. Linguist Ketchem Molik delves into the concept of reference states and dimensions, shedding light on the interpretation of such a scenario.

The video goes on to portray three different scenarios involving the glass of water, including a traditional air-water glass, a vacuum on top glass, and a vacuum on the bottom glass. As the vacuums appear at time T equals 0, a series of fascinating events are set in motion.

Initially, air molecules gradually drift into the vacuum, leading to a boiling effect in the water as water vapor is shed into the empty space. The presence of a vacuum creates a shock wave when it collapses, causing intriguing interactions within the glass of water.

As the vacuum collapses and air rushes into the glass, a pressure wave is generated, resulting in a loud bang and visual distortions of the glass. The dynamic forces at play, such as air pressure and suction effects, culminate in dramatic outcomes, with the glass ultimately breaking under intense pressure.

The video vividly depicts the water hammer effect, showcasing the immense force generated when the water impacts the bottom of the glass, leading to its shattering. The subsequent events, including the glass rising and breaking against the ceiling, offer a mesmerizing insight into the intricate physics involved in such a scenario.

In conclusion, the video 'What if a glass of water were LITERALLY half empty?' provides a captivating exploration of the unforeseen consequences that may arise from a seemingly simple occurrence. It serves as a reminder of the complexities of physics and the interconnected nature of various forces that govern our physical world
