You probably don’t want to do this. People will get salty and DDOS your server. I ran a KF2 server for like 5 years and eventually the traffic overwhelmed my connection and I had to stop.

I learned about these from the projectionist where I worked, back when I was a kid. When they’d get taken out of a projector and thrown in the garbage, he’d smash them on the ground to get the tungsten electrodes out. Apparently they both looked cool, like the surface of the moon, and sold for a lot!
