The summary of the text is:
The text is a transcript of a video by Grigory Sokolov, who demonstrates different types of fires for survival in the forest. He explains the advantages and disadvantages of each fire, such as how long they burn, how much heat they give, how much firewood they consume, and how to prepare them. He shows four types of fires: the fire leg, the fire binoculars, the fire wasteful, and the fire hanging. He also compares the combustion rate and area of different wood shapes, such as logs, shavings, and branches. He gives tips on how to sleep near the fire and how to cook food on it. He invites the viewers to visit his YouTube page and VKontakte for more videos.
Hi, this is Copilot. I can help you extract the key facts out of this text. Here are some facts I found:
1. The text is a transcript of a video about different types of bonfires and how to make them.
2. The author demonstrates an experiment with a log and shavings to show the difference in combustion rate and temperature depending on the surface area.
3. The author compares three types of bonfires: fire legs, fire tracers, and fire around.
4. Fire legs are economical and long-lasting, but give little heat and require logs without knots.
5. Fire tracers are wasteful and hot, but easy to make with small firewood and suitable for extreme situations.
6. Fire around is a variant of fire tracers for deep snow, where the logs are suspended in the air and supported by poles.
