Observe the strange chemical behavior of frozen acetone in nitrogen

vt.physics on Instagram: "The Science of Ice Plugs: Repairing Pipes with Liquid Nitrogen! In a clever application of physics and engineering, technicians have found an efficient way to repair high-pressure water pipes - by freezing them. Using liquid nitrogen, which boils at –196°C, they rapidly cool a section of the pipe, causing the water inside to freeze solid. This frozen mass temporarily blocks the flow of water, effectively acting as a valve without the need for mechanical shutoff systems.
