GREENPOWERSCIENCE | Solar Key Making DIY keys with a Fresnel Lens Melting Pennies With Fresnel Lens Solar Power @GREENPOWERSCIENCE | Uploaded August 2013 | Updated October 2024, 1 week ago.
Fresnel Lens melting pennies is illegal for metal collecting. Pennies made of zinc melt quickly. You can buy zinc pellets as an affordable metal. If you need to copy a key that the hardware store cannot do, this solar method works with most keys for locks.
Thank you to ZeroFossilFuel for the wireless mic.
