-with this ingenious phase-change mug prototype, your coffee will cool to a perfectly drinkable 140 degrees and stay there for hours.
-"Our goal was to create a coffee mug that will take piping hot coffee and cool it to a hot, but drinkable, temperature—and keep it at that temperature for a long time," Logan Maxwell, the co-creator of the aptly named Temperfect mug, told R&D Mag.
-The secret of the mug's temperature-control abilities is its unique insulation material.
- uses a three-wall design—an inner wall that holds the liquid, an outer wall that you hold, and a middle wall separating them
- Maxwell injected a proprietary nontoxic phase-changing chemical. This material is a solid at room temperature but will melt into a liquid when heated by the coffee.
