This is how I remember it too. However, we did it to have "visions."....
You know, after I posted my original statement, I thought about it and decided this game was probably our pre-teen's version of using hallucinogenics. (One couldn't actually buy pot in elementary school in those days.) I don't remember what if anything was said about it and it wasn't something we spent a lot of time doing. Just a way to deal with occasional boredom, IIRC.
