While there is some clever thinking at play here, unfortunately Captive is not something that will
play well for me.
A few things to note when deciding.
1 - The cap is "dirty"
after falling, meaning it is critical that the performer and not the spectator retrieve it.
Afterward, it "could" be handed over for casual inspection, but I don't believe would stand-up to
any real scrutiny.
While I typically stray away from allowing examination of props, this
is already on the table and they will be inclined to reach for it, particularly in small groups.
Audience management is a must, and I'd strongly recommend placing it under a cup as seen in the demo
to help with this.
2 - The reset is not something that can be done within eyeshot of
anyone. It is not complicated, and is pretty quick, but will require a degree of privacy to
perform..
On the upside, if you can get past those negatives, the big positive is that the
angles are very good.
Also worth noting is that mine came almost dry, to the point that the
internals would need to be swapped out to use it.
