Who are these people rubbing paper on bits of metal anyway? That seems a pretty stupid hobby. Is this being done by people you konw? Like a club or maybe a gang?

Don't you realize this is a gateway drug kind of thing? First you start with paper and iron. Then it's emory cloth and titanium. And before you know it, you're hooked and stealing - or worse - to support your sandpaper and ceramics habbit!

Get out while you can!

The answer is ……..

Look at the properties of the metals.

The white paper is a bit of a red hearing, the fracture would cut the paper to shreds.

i) Cargonite.

It's a little known grey semi-metallic liquid that is a solid at room temperature.

Often confused with Kryptonite, it produces a grey appearance on paper and when held up to sunlight turns red.
