Smithsonian G-Cell Orange Juice Clock Kit Product Description

The Orange Juice Clock has been a popular science demonstration for nearly 10 years! It takes a magnesium strip, a copper strip and juice in a beaker and makes a galvanic cell. -- Using something as simple as orange juice, the G-cell clock visually shows how chemistry or more precisely, electrochemistry is responsible for the common phenomenon of a clock ticking. -- The chemistry of the process can be understood on a variety of levels, from middle school (simple electron flow in a circuit and Ohm's law) and high school (reduction/oxidation and standard cell potentials) to first-year college (cell potential at non-ideal conditions) and graduate school courses (overpotential and charge transfer across interfaces.)
