science show?
Physics 101
Science as to the beach ball staying up in the air about a couple of feet above a vacuum cleaner. Not a mystery, but Bernoulli's principle, sometimes demonstrated in high school science classes. I was always fascinated with the ball. Sometimes it would be tilted off from center of the vacuum cleaner and would still stay up, Coanda effect.

Sears had science too - you could stand on a thing and get an Xray of your feet in the shoe department.
I remember this too. There was a shoe store in town that had this serve. We thought it was cool to have our feet X-rayed. Just shows what little they knew about x-rays back in the 50s & early 60s.
