Today we’re gonna play a guessing quiz.
First, pick a little marble from your drawer.
Then push it into a mystery box, whose core
is like a maze of many paths. Now, whizz,
Look at the ball when it comes out and guess:
Which way, inside the box, did it go through?
Was it path number one, or three, or two?
Let’s try and assess your chances of success.
If your marble’s a cheap, generic brand,
the various paths won’t have that much effect.
But, if you choose a rather high-spec ball,
With every different turn, during its roll,
a distinct shine the sphere’s going to reflect.
Just spot the change and win! Do you understand?
Let me briefly expand
and give you the tagline (pardon the garble):
Every quantum resource is a good marble.
