Interesting to see what they make of it.

I recall having fools gold in my rock collection for my Boy Scouts merit badge in rocks and minerals.

And I could not help but notice that the metal part of the thing was magnetic by itself.

They should try this with a completely non magnetic metal

Be cool if we could eventually replace a lot of rare earths. A lot of pollution in their mining.
