Can a pineapple light a light bulb?

Answer 1

Yes, if you had differing metals, maybe from opposite sides of the period table. The citric acid would act as an electrolyte and cause electrons to move between the electrodes. I think you'd only get about a half volt in such an arrangement, so generally you'd use 3 lemons in series to power a watch. Maybe 6+ would power an LED, but test and see as you go, it may take less. A volt meter would help so you will know the polarity and the amount of voltage you are getting.

Also, you might want to try limes. They tend to be firmer and might last longer (in terms of spoilage). You don't want a science fair project to rot before it can be judged.

Answer 2

the acid makes the lightbulb light. but 1 lemon does not have enough acid to light a lightbulb. you need at least 4 lemons to light even a small light bulb.

Answer 3

No of course it cant becuase it has no electric content.....

Answer 4

Yes

Answer 5

Answer 6
