Like a Hot Knife Through Butter ...with a New Twist
My son-in-law, Matt, showed me this video demonstrating the incredible thermal conduction property of graphene. A miracle material for seemingly every other realm of physics, thermo-conductive pyrolytic graphite (TCPG) conducts heat with twice the efficiency of diamond, and 6x the efficiency of copper and silver. Because of the extreme thermal conductivity, the heat from the guy's fingers is enough to slowly force the graphene sheet through the ice cube. In the future, the colloquial saying for expressing how easily a material is cut might change from "like a hot knife through butter" to "like a body-temperature graphene sheet through an ice cube."
