When opened, the Hoberman Mega resembles a colorful geodesic dome with a diameter of approximately 1.5 metres. But the structure folds down to a fraction of its normal size thanks to the scissor-like action of its ingenious joints. When open, six latches safely lock the sphere in position. Roll it around, climb inside or just look at it in wonder.

Activity and game sheet included.
