I really need to break this down because it sounds like the ramblings of someone having a stroke or something...
40-50 seconds is the point where most Mr. Wizard experiments with a speedcube begin. Did you follow the steps of the scientific method?
You gotta keep going until you hear the satisfying "loud pop", am I right???
Apparently you've never put anything metal into a microwave before this experiment.
Seems like a natural thing to do to a smoking cube. My parents always taught me, if you don't have a fire extinguisher handy, use the nearest aerosol spray available.
Another obvious follow up.
I'm not exactly sure how intentionally subjecting your cube to the most bizarre and convoluted torture ever thought of, and the cube still functioning counts as "irony."
