Horror of Horrors!

"I wish... I wish..."
"Yes?" the genie prods. "What do you wish?"
Your thoughts race. "I wish I had a ton of gold!"
A funny smile crosses the genie's face. "Done!" he declares.
You glance around. Nothing seems different.
"Where's my gold?" you demand.
"Look up," the genie replies.
You peer up into the sky. Twenty feet above you, hanging in midair, is a glittering globe of gold about the size of a basketball.
You remember learning in science class that gold is one of the densest metals there is. Even a huge amount of it doesn't take up very much space.
But unfortunately for you, when it falls on your head, it still weighs a ton.
