You often hear people say, "Well, that 1 thing was worth the price of the book".
In this
case, that's exactly right. There is a "bit"...just a tiny thing...that totally is worth the price
of the book. (And I'm not saying which one.)
And I'm not saying there's ONLY this one bit.
There's a bunch..which I'll probably end up using.
But there's one bit...that I will
DEFINITELY end up using, and it will make the trick into a double applause trick, with a doubly
magical ending.
So yeah...it's worth it.
