Nobody makes that even for oil, least for burritos lol.

The part about magnets and aluminum foil was the giveaway for me. I knew aluminium foil wasn't ferrous but apparently the author didn't.

Being conductive may be enough.

Search for videos of a copper ring falling slowly on a strong magnet (or vice versa); eddy currents create a strong magnetic field.
