factory smoke
Factory smoke is the magic inside your gadgets. If you break it, you kill the magic. No more working. Just a sad, dead gadget.
I broke my phone with a hammer. It let out all its magic and died. Now it’s just a broken piece of junk.
My TV died because I poured soda on it. It let out a final puff of factory smoke and quit.
My game console died because I used it as a stepstool. It let out all its magic and got sad.
