In action movies, we often see scenes where the main character, along with their car, plunges into a river and then easily breaks the door to escape. This scene is often considered fictional and unrealistic, but it remains a hot topic of debate in online communities. To find out whether a car door can be easily opened when submerged in water, a daring YouTuber decided to become the protagonist in this scenario by submerging himself along with his car in deep water.


The main character in this story is Heohop, a male YouTuber who recently caught attention by releasing a video titled: “Can the door open when the car is 100% submerged in water? I tried“.
In the video, this YouTuber attempted to submerge himself along with his car in a gigantic tank that was 1.7 meters tall, filled entirely with water. After unlocking the sunroof and disconnecting the car battery, he threw himself in. It didn’t take long for the car to be submerged, with water rising above the dashboard and air conditioning. When the water level reached Heohop’s neck, only about 30cm remained until the roof, he decided to open the door.

According to what happens in movies, the door should open easily. But no, the water pressure, even though it wasn’t too deep, was already substantial, and Heohop, despite his efforts, couldn’t open the car door. He admitted that it felt like he was under pressure from the outside.

A second experiment was conducted. This time, Heohop waited until the car was full of water, completely submerged, before attempting to open the door. Surprisingly, this time, the car door opened very easily. Heohop tried again and found that the result was still the same: it opened very easily.

The YouTuber later expressed great satisfaction with this experiment but also admitted that during the water filling, the feeling of fear had overwhelmingly taken hold of him. In the comments section, many expressed their admiration for the recklessness, investment, and scale of Heohop in creating such a video. After all, submerging a car also costs a lot of money.
