Chisanbop seems like a valid and useful technique, but for $12.99 in 1979 dollars? These days there are websites and youtube videos, but how hard would it be to get in 1979? I suppose it depends on the size of your local library/inter-library loan.
Pre-internet (I think) but more recently than 1979 I did get a book on making holograms via inter-library loan.
I don’t want this thread to discuss the value of Chisanbop , just on how a parent could get info on it without forking out $12.99 in 1979 dollars.
A quick look at Amazon shows there were several books about Chisanbop published in 1978-79, so any city with a moderately progressive bookstore or a really up to date public library probably carried at least one of them.
As for the $12.99 price tag, a pair of non-designer blue jeans typically cost $10-$15 in that era.
I can remember the teacher parents of my childhood bestie teaching it to me in the early 70s [certainly no later than 75 because they moved to Pittsburg at that time]
They were involved in teaching the impaired [mainly deaf and mute] and had neat stuff like that balance board and edutainment type games. May have had something to do with that, or they just liked learning and teaching odd stuff.
Thanks for the link @Bullitt . I had NO idea what was being talked about.
It’s interesting though. My wife and I play a lot of darts. You add up your scores to 501. Mostly easy to do in your head, but sometimes a system like this might help. 177 + 21 + 9 + 18 sort of stuff. Easy really, but this could be a double check.
Had the OP written their cite so it expanded into a preview of the post they were springboarding from, instead of just posting a bare link, there’d have been little reason to question.
It’s nice to make hijacks or spin-offs as separate threads. For sure the Mods have been bugging all of us to do that more often. I’m certainly guilty of failing to spin-off when I ought to.
But if anyone does spawn a new thread, they need to be clear in their mind that most posters will not come to the new thread from the old thread. They’ll find the new thread on its own and will lack all the context provided by the old thread.
So your OP needs to provide all the relevant context and background.
The first (and only?) time I heard about Chisanbop was an article in one of those Scholastic magazines like Dynamite or Bananas (circa 1980). I think it was pretty vague on the details.
I remember hearing about Chisanbop (which my childhood ears heard as “Chisholm-Bop”) when I was in grade school in the late '70s, and seeing people demonstrating it on TV; however, I don’t think I recall ads for tools to learn it, as mentioned by the OP.
The name became sort of a punchline for “making funny gestures with your hands” in my grade school for a short time. We all knew what Chisanbop was, at least a little bit, but it wasn’t a technique that was taught at our school. It seemed, to me, like a fad that was well-known for a little while, but faded.
