The fact that he pours the straw out of the bottle at the end of the demo video led me to believe
that the straw can be handed out for examination. Not so. I wouldn't have purchased this video had I
known that ahead of time. In close-up or walk-around, I welcome having spectators examine my props.
While I'm sure one could figure out a way to switch out the straw, I seriously doubt I will ever use
this trick.
