This really doesn't matter. There's just no way that you'll choose to hazard a guess as to what is in my bag, and you won't hazard a guess as to what is in Randi's sealed box. This is because you know there's too high a chance you'd be wrong.
I would be much more impressed if you named the contents of my container than if you named what's in Randi's. That is because it would be personal. Something I can personally verify. Again, I know quite well that this 'spirit' of yours will choose not to bother. You'll probably just give us all some crap about how it requires faith rather than evidence. Alternatively, you may just draw this on for a long while, then vanish from the board.
So here's the challenge. Tell me what is in this small leather bag. It's sitting on top of my desk. To make it a bit easier, I've put a small piece of paper on it that says "this is the secret object". Surely that will help. Tell me what is in the bag, and I will probably start to believe in spirits.
Incidentally, last night I promised my sister that I'd give her a thousand dollars if you managed to come up with the answer. Mind you, it's a thousand bucks Canadian, but it's still money. I estimate about a one in a billion chance that I'll have to pay her anything.
You have three days left. Please, please tell me what's in the bag. You'd really impress me.
