FREE BUT VALUABLE - https://vk.cc/9Vab4t Hello, guys! Today we decided to test an unusual experiment! I have long dreamed of doing something with nitrogen and hurray! We thought about why not freeze a rail in nitrogen! A rail! You understand how this can end, right? Will nitrogen be able to freeze the metal structure so much that it loses all its strength properties? Today we will conduct several experiments with nitrogen, which you will probably be interested to watch!
