Greetings,
We are currently working on a exhibit that illustrates space in 3-D. The concept is borrowed from the Einstein exhibit "Space-Time Table". Its essentially a rubber sheet showing the "X" and "Y" axis. Guests place spheres of different size and density on the grid to form a "Z" axis. My question is one of safety. Often times when an exhibit is being developed we
have to ask ourselves "How will the 1% of guests use or abuse the exhibit in a way that is harmful to themselves, other guests or the facility." With that being said, has anyone had experience with a exhibit that used loose spheres weighing up to 5-7 pounds? If so, what was used to promote proper usage of the exhibit? We really do not want to tether the spheres due to tangling issues and lack of freedom to explore the different properties of "curved or bent" space. Any input would be greatly appreciated.
Cheers,
-Doug
