Tomato Battery Powering One LED and a Buzzer

Just wanna share about this one nice article i just read from elperfecto.com about this tomato battery.

I was amazed about this tomato battery that can power up the LED and buzzer.  When i was in high-school, i remember we did an experiment about lemon batt.  powering a small calculator.  We had about approximately 10 lemons to power up the small calculator.  Lemon is the commonly used fruit in the science project to make a batt. and not a t0mat0.  So i was amazed to see this one t0mat0 powering a LED and a buzzer.  The t0mat0 batt. only uses two metals: zinc and copper dipped in mashed t0mat0. The t0mat0 batt. in the video was able to  give about 3.5 volts enough to power up the LED and the buzzer.  According to the author,  “Acid can release electricity from metal” and one good source of acid except from the lemon is the t0mat0.  Watch the video below to see the t0mat0 battery at work.
