The Wheel-O was one of those toys that really didn’t do much. It was fun for about five minutes and then you either put it down, or you found other uses for it. For me with just a bit of kite string, it made a great spinning top.
Then it made a great projectile for throwing at your sisters or brothers. Every kid I knew had one sitting on their dresser gathering dust. Of course you have to understand that there were no video games in the 70’s with the exception on pong.
