How do you guys like to climax and make the reveal at the end?

It is never up to us guys, but always up to the significant other.

Could you be more specific, what you are referring to? Is it the self inflating foil balloons?

This is not a magic effect, and I have not seen it performed as such, or in a magic performance.

Or are you speaking about the Paul Harris card effect, Wake Your Pack.

There is no general answer, but much of it has to do with your personality.
