Metal contaminants? Sure. But enough metal to stick a magnet to your skin? From a clearish liquid? It would take a large nail or a rod close to the surface for a magnet to stick. Besides, lick a coin and it will stay on the skin the same way. It is a scam.
I swear, science might as well be magic these days....
