I did this experiment(and some others with my Cub Scouts den a couple of years ago. We used it as signaling device to play with Morse Code. We also made electromagnets and worked on soldering. These are great learning experiences for the Scouts and fun to boot!

I hate to be “that guy” but this is quite illegal. Defacing currency (specifically, sanding the copper off one side to reveal the zinc core) is in violation of US Code Title 18 Part 1 Chapter 17 which states that whoever “alters, defaces, mutilates, impairs, diminishes, falsifies, scales, or lightens any of the coins coined at the mints of the United States…shall be fined under this title or imprisoned not more than
five years, or both.”
You left out the first two words: “Whoever fraudulently alters, defaces …” This use is not fraudulent.
LMAO, you hate to be that guy yet you are exactly that guy. I bet you are the life of the party… that is IF you ever get invited to any.
How long did it take you to google that then copy and paste it here, all for the purpose of being a jackass. I bet it took longer than if you had just replied with “thanks man, cool post”
Does anyone know off-hand if this works with British pennies (£0.01UK)?
HAHAHAHAHAHAHA!!!!!!!!you guys are so f***ing funny! good day. ;)
