This video is about a group of people conducting experiments in a room filled with helium. They start by brainstorming ideas on what to do with 100,000 rubles (approximately $1350 USD) and decide to fill a room with helium.
Once the room is prepared, they conduct various experiments, including:
* Measuring the sound level in the helium room and comparing it to a normal room
* Testing how a makeshift ship behaves in the helium room
* Observing how a humidifier works in the helium room
* Examining the behavior of a broken light bulb in the helium room
* Launching a quadcopter in the helium room
* Testing how fire behaves in the helium room
The experiments show some unusual results, such as the sound level not changing, the makeshift ship not floating, and the fire not burning in the helium room. The group also notes that the equipment they use in the helium room, such as cameras and speakers, can malfunction or not work at all.
Throughout the video, the group is enthusiastic and excited about the experiments, and they encourage viewers to subscribe to their channel for more content.
Here are the key facts extracted from the text:
1. The experimenters spent 100,000 rubles (approximately $1,350) on helium cylinders.
2. They considered various ideas for the experiment, including filling a room with helium.
3. Helium is about 8 times less dense than air.
4. Sound conduction is 8 times worse in helium than in air.
5. The experimenters created a helium-filled room to test various phenomena.
6. Two Gopros stopped working in the helium room.
7. A light bulb that was broken in a normal room worked for 2 seconds in the helium room.
8. Steam falls in helium, but rises in air.
9. A quadcopter designed for air did not fly in the helium room due to the lower density of helium.
10. Fire does not burn in helium.
11. Matches did not spark in the helium room.
12. An inextinguishable match smoldered but did not burn in the helium room.
13. Bengal lights had fewer sparks in the helium room.
