Product Details

Water Powered Digital Clock
by American Scientific
 
 
This clock is great as a science teacher's present or as a present for children showing interest in the science of things.  The clock can be used as a learning tool in classrooms especially because it includes lesson plan ideas and a picture of the simple circuit that creates the battery power.  All you need to do is fill the reservoir with water, (de-ionized water will not work), and this clock starts working.  Inside the reservoir, the water's contact with electrolytes in the two metal pieces causes battery energy to be generated.  By adding just a bit of lemon juice you can help to enhance this process.  The only maintenance required is to change the water periodically. 
 
The clock measures about 4 inches x 3.5 inches.  (Instructions and lesson ideas are included)
 
Ages 8 and up.
