That's what I was thinking - a big ass electromagnet to collect up any metal thrown in.  Silverware, rings, loose change, iphones, ...


Not all metals are ferrous, stainless steel flatware for example would pass right through even a big ass magnet.

I imagine that people going to the trouble of installing a system like that would ensure that the cutlery they used was suitable for it.

Not too good for those of us with pacemakers!
And if the 'silverware' is Sterling Silver and the rings 24ct gold, how would that work?
I don't know about US loose change, but here in the UK, coinage is non-ferrous.
