Hot coffee can do a lot of things besides perk you up. For example, it can make Dragon Ball characters go Super Saiyan and it can determine whether or not you’re crazy. Apparently, it is also capable of powering a teleportation machine:
You get to be a member of the transporter room crew when you add a hot beverage to this Star Trek Transporter Heat Change Mug. Watch Captain Kirk, Mr. Spock, Lieutenant Uhura, and Dr. McCoy slowly disappear from the transporter pad on one side of the mug and reappear on the planet surface on the other, faster than you can say, “I’m a doctor, not a barista!” But don’t worry, they’ll return to the ship as the mug cools. Presumably to get more coffee.
