How do i shrink it back if it gets stuck fully expanded from kids opening it to wide?

This "toy" is not designed to come apart. However, I talked with an engineer who "plays" with a larger one and he said to start at the place where it is loose and trace it back to a spot what is tight. See if you can loosen th tight segment and perhaps it will open the entire shpere. It may be necessary to sheck several of the circles. There are so many. It may be a lot of fun to try this approach, but time is valuable and it may be necessary to buy another one and hand the stuck one on the ceiling as a reminder to be gently on a fragile toy. (I use it to demonstrate how the Dural tube may respond to the birthing process or to a head injury) Good Luck to you.

What's the diameter of the sphere when it's fully expanded?

I don't have it here, but when I use it at school for a demonstration of taking deep breaths, it expands to about the size of my chest. Perfect

How is the list price is 500 the list price is no where near that?

Yes, the $500 is incorrect.....the actually list price is $17.99.
