  • Expands from 9.5" to 30"
  • Page with ideas for 21 Cool Things to Do

Two videos featuring the original Hoberman sphere follow. The one on the left (or top) shows the geometry of an open sphere. The video on the right (or bottom) uses a closing sphere to model the collapse of a star.

Our kids like to play catch with an open sphere. The challenge is catching it open and allowing it to close just at the right time. This game is restricted to outdoors at our house.

Fully expanded Hoberman sphere.
