Water Clock, Green

Item 9456-40

All you need to do is fill the reservoir with water and this clock starts working. Because the water is an electrolyte, it allows two metal pieces to act as a conventional battery. By adding a bit of lemon juice, you can help to enhance this process. The only maintenance required is to change the water periodically. • Comes with a Teacher’s Guide • Color: green • CE certified • Approx. 4″ (100 mm) W x 3.5″ (90 mm) H
