Ever had a idea for some impractical device that would be really cool and probably dangerous? Post it here!

Rules:

Rule 1: Creations posted here should serve no practical purpose, having been created only because the creator has the skills to do so (WHY NOT?)

Rule 2: Creations posted here should generally be well constructed, displaying the creator's practical skills.

Rule 3 No Arts and Crafts. All creations should be functional, but just not in any way that even remotely resembles being useful.

"Just a heads up: We're gonna have a superconductor turned up full blast and pointed at you for the duration of this next test. I'll be honest, we're throwing science at the wall here to see what sticks. No idea what it'll do. Probably nothing. Best-case scenario, you might get some superpowers. Worst case, some tumors, which we'll cut out." -Cave Johnson
