Hey I need help with a science ex. How do you make a clock that runs on grapefruit acid????????

Question

Just a symple one
( please list supplies)
THANK YOU!!!!

Answer 1

use the grapefruit acid as a catalyst.. and a thick copper wire as the cathode and a steel nail covered with Zinc ( galvanized ) or even Zinc itself as the anode. hook those up to the clock by wire and majic!...zee current vill flow and zee clock she will tick tock!

I may have the anode and cathode mixed up but I think that is the outcome the ex calls for.

Answer 2

you need an anod and a cathode, copper and zinc work good. The just connect them to the DC input. Please not, your clock will need to use very little power to work. You usually get about 3~5 volts out of a good grapefruit.

Answer 3

Insert one carbon and one iron rods into the grapefruit and the chemical reation will create electicity or 1.5 volt.

Answer 4

You should check this out. It shows lemons, but just switch lemons with grapefruits and it will be the same.
