Magic Tricks

In the first moment it looks like a real copper cup, it feels cold and the weight seems also ok, but stop, there is something wrong. The sound if you put two of them together is completly different from real copper cups, because it´s not made from solid copper. The cup sounds like a copper plated or painted plastic cup. And I think because it is a copper plated plastic cup. But if you don´t reveal this secret to the audience, they won´t notice that fact.
The rest is ok, the magnet is strong enough, the handling is also ok. I just hope that the copper finish will hold and not peel off from the cup.
