Warning, don't try what you are about to see without understanding the risks. Aluminum foil will reflect the laser back up and out of the laser engraver and possibly blind you... With that said... someone asked in a comment if the K40 can cut tin foil. I don't have tin, but I do have aluminum foil. The results were unexpected and awesome!! Enjoy and thanks for watching!
