An "aha" minute hits more deeply after some set-up.

You need to set up the mystery, and then have things click into place.

The satisfying snap of the surprise that in retrospect feels obvious.

A great magician knows the real trick is the setup.

Without the setup, the magic is just a confused person at a table.

You have to make the audience want the thing before you show them you can do it.
