Can the K40 Laser Engrave Metal? REVISITED!

Can the K40 Engrave Metal REVISITED!!!

Testing and experimenting with my Subscribers comments and suggestions!
Can the K40 Laser Engrave Metal REVISITED, a packed video with multiple experiments that can be considered as alternatives to professional marking sprays!
Yes, i will try out Dry Moly Lube Spray, try to etch metal in a saltwater bath and try to engrave Metal with toothpaste!

Disclaimer:
Even it looks fun of making those experiments i am far away when operating the laser and not even look at the machine when it is operating! The invisible coherent infrared laser light reflected off the working materials can be dangerous to your eyelight! You should never operate the K40 Laser with the lid open!

I hope you like your ideas, Enjoy!
