This AFK Player Trap will be a perfect way to troll AFK Friends, and make them hate you!

To use, weld to the ground, and place the player on the blue platform.
Either push them with a car, push them with your own character, or build some janky piston system to get them on the platform. Once they're on, press the green button to activate the machine. If you decide to be kind, release them with the red button.

If you place the red button, you will have to re-weld it to use it again.

I've never been able to escape this, so have fun!
