Oh the Belt is effective! I totally agree! Because it's the belt that's the result if you drop the penny ! your having to hold pressure with your nose on the penny, your legs get tired , they start squirming around, it's physically demanding , ya can't see what anybody else is doing , especially if everybody else is doing something cool.IDK. This is a new one on me. We got beatings growing up so I don't know any other way...
I was a pretty tough kid & I could take a good whipping ! but i hated the wall
