Creepy video shows you how to make batteries out of lemons

Forget concepts! An instructional (albeit a bit creepy) video from Hila Science Camp shows you how to make live, working batteries out of ordinary pieces of lemon. The process is faily simple: all you’ll need are a few inches of wiring, a nail that’s coated in Zinc, a copper penny, and of course, the lemon itself. Where would we be without Science?
