/diy/ - Do It Yourself

>>2388735
Imagine if instead of plug holes, my wall had just 2 big flat exposed metal buttons, and instead of plugs my devices only had exposed wires, so i could power a device by just having the wires touch both buttons (and maybe fix them with duct tape or something).
Could I theoretically power any number of devices I wanted by connecting all of them to just those 2 buttons if I were careful enough to keep the wires from touching each other (see pic related)?
Yes I know this would be extremely dangerous, I only wanted to know if it's theoretically possible.
