Lemon Battery - With Real Lemons

I had enough with all this making-lemonade-from-lemons chatter and instead just made some light. It’s so freaking easy (provided you remember to grab the wire strippers before you head to the kitchen). Copper and zinc etching plates are probably $7 at your local art supply store. If you want some detailed instructions, check Danger’s Closet, but the better way to proceed is (a) look at picture, (b) implement.
