Steve Spangler, a well known science teacher who has done some fun experiments on Ellen, demonstrates how to make pennies look like gold coins to lure pesky Leprechauns into a trap.
One way to trick your kids into thinking there was a Leprechaun in the house is by putting green fizzers–tablets that turn water green–into the tip of faucets, shower heads, or toilets.
After heating the zinc mixture, you drop the pennies into the 100 mL cylinder and the coat of the copper pennies becomes the color of silver. Then to fuse the zinc and copper together, heat from a torch is used until the color of the pennies turn to gold.
