what are your door handles made of?

You remember of course our little puzzle; the one where we found that there are some metals, like gold…..


and ‘door-handle’…..


that do not stick to a magnet.  Well, some of us did a further investigation in which we tested different kinds of metal to see which of them would stick to a magnet.

We tested brass…..


and copper…..


and iron.


And a few other metals besides.



is what we found out.


And now we think we know what our door handle is made of.  I wonder; what do you think?

(PS How on earth did we get from a fishing game to door handles?)
