Hoberman Sphere, Liberty Science Center

“One of Chuck Hoberman’s best-known museum pieces, the original Hoberman Sphere was installed in 1992 as the central exhibit in the Liberty Science Center’s atrium. The sphere was re-installed in 2007 in the newly renovated museum’s entry hall. Suspended by cables, the 700-pound aluminum sphere expands and contracts smoothly and continuously. Throughout its long history, the sphere has become the icon for Liberty Science Center, logging millions of cycles”

  1. The first time I saw the Hoberman Speher was November of 1992, two months before the Center opened to the public. I felt giddy at its movement and it took me awhile to realize that it was on a ~20 minute cycle, which (in my PR role)I described to the press as a computerized dance. Now it hangs in the vast entry hall of the Center’s new wing, still amazing people of all ages and from all walks of life. Even if I am not within view, I know when it has reached the part of the cycle where it suddenly pops open, because I can hear the thrilled screams of schoolchildren reactying to the sudden and unexpected moevement. It really is one of the truly iconic objects in any science center I have ever seen.
