I’ve been thinking about those large spherical Christmas ornaments on display at Barton Creek Square Mall. Are they rigid, or do they somehow fold into a smaller shape for storage?
Recently I saw one in a non-spherical status, and that explained everything. They are inflatables, like the Santa on my front lawn.
The fan is in the top, hidden by the red ribbons. Power for the fan comes from above. Internal access is accomplished (probably) by a zipper under the flap of material to the right of the top. The ball is held open by air pressure.
I doubt that many others wondered about this, but it has puzzled me for at least 2 years. Now I know.
