This pipe can be repaired without shutting down the entire water flow. The secret is liquid nitrogen. Pouring liquid nitrogen into the pipe at minus 196 degrees Celsius freezes the water to form a strong ice block. This ice block can withstand the pressure of the water, allowing the next section of pipe to be repaired or cut without shutting down the main line.#liquid #metal #pipe #nitrogen #technique #technology #tech #education #facts
