The routine I’m working on for The (W)hole Thing by Emerson and West is intended for for family/adult audiences. The other day I threw it in my case when I went out to do some summer camp shows:
I thought the concept of the whole/hole wouldn’t hit with kids. Much to my surprise the kids liked the trick and got the idea of the verbal concept behind the routine. For the trick to work, the kids need to be able to read, so I probably wouldn’t do it for kids much younger than second grade.
Now I’m just waiting for my custom cards to arrive from the printer, so that I have a fancier set that what I made for myself.
