They certainly were super. These wonderkins of the ball world would bounce higher than any other ball I have ever seen. They were perfect little wonders of modern science with the only one problem, when you were a little “super” with your ball, they would split in half down the “seam”.
When I was a kid, I would fantisize about having a house with one single special room. This room would had no windows or doors, and solid concrete on the walls, floor and ceiling. The endless superball bounce was my dream.
I would have that today, just never figured out how I would get into a room with no doors…
