Green Science Lemon Clock Kit
from KidzLabs® and 4M®
What?! No Batteries?! That's right! Run a clock off of 2 lemons!! Finally, a scientific chance to play with your food! -- Learn about electricity and chemical reactions in an innovative way. This unit is designed to demonstrate the principle of an electrochemical cell.-- Can two lemons allow you to generate enough electricity to run a digital clock ? Just push the zinc and copper electrodes into the lemons causing an oxidation/reduction reaction that is converted to low voltage. -- You can also try other fruits, vegetables and beverages to see what works like: -- Apples -- Avocados -- Bananas -- Cucumbers -- Potatoes -- Limes -- Oranges -- Salt Water -- Soda Pop -- Tomatoes -- the possibilities are endless!
