This idea combines two basic concepts, one of which has been used for drawing predictions before (I
first saw it in a Bob Cassidy product, but it may be a lot older than that). The other is fairly
obvious from the title. The ideas shared by Luke Jermay after the basic instruction are very
valuable and they will help to really get the mind working.
This will not work with index
cards. You need either business cards (glossy both sides) or double-blank playing cards. I tried
with index cards and there's just too much paper texture to spread smoothly.
Overall,
this is one that you will have to assemble yourself, but it isn't a terribly difficult job. I would
also customize the list of possible drawings to reflect your local likely choices. There are also
ways you can narrow the possibilities by what you tell your participant. "Imagine you were in 3rd
grade and the teacher passed out paper for art time. Think of what you would have drawn on that
paper."
I don't think this is for everyone, but I do think it is a very useful idea.
