Plus it made it easier for them to show it off to their friends, "Look,

it's hollow," (shake, shake).

Now that's a good idea. I know what you mean about them not having a
clue of what they have in their hands. I know some are so uneducated
that they don't understand that a maple ball with an ebony icicle is
not accomplished with paint. Hollowing is completely out of their
sphere of referenece.

You may have something there...
