The video is about an experiment where the host, Vlad, attempts to solidify mercury using liquid nitrogen. Mercury has a melting point of -40°C, but it can be solidified at temperatures below -200°C, which is the temperature of liquid nitrogen.
Vlad starts by pouring liquid nitrogen into a container and then submerging a bottle of mercury into it. After a few minutes, the mercury solidifies and Vlad is able to hold it in his hand. He then melts the mercury and pours it into a container, where it solidifies again when liquid nitrogen is added.
Vlad also demonstrates how mercury can be forged into different shapes, such as a knife, by pouring it into a mold made of modeling clay and then solidifying it with liquid nitrogen. The resulting solid mercury knife is heavy and malleable, but also very fragile.
Throughout the video, Vlad emphasizes the importance of safety precautions when handling mercury and liquid nitrogen, and warns viewers not to attempt to reproduce the experiment without proper equipment and protective gear.
Here are the key facts extracted from the text:
1. The temperature of liquid nitrogen is approximately minus 200 degrees Celsius.
