Calling all physics teachers: This slick, semiconductor-based unit demonstrates the Peltier effect (conversion of electricity into heat and cold) and the reverse Seebeck effect. Designed to work with a couple of standard foam coffee cups. The unit has a Peltier junction sandwiched between (2) 1-3/4" x approx 7" long aluminum brackets and is connected to a small DC motor with a blade, (2) banana-plug sockets, and a switch between them. Good instructions, despite their spelling Peltier as "Peltire." Made in the U.S. for Pacific Science Supplies, Inc.
