TETRA 20

For the engineer or puzzle fan, 9 to adult

$30.00

The natural finish woodgrain version of TETRA is easy to manipulate into different sculptural forms but difficult to form into a Tetragon. It comes as 20 attached balls in a single plane, to be solved 

by turning and/or folding balls until the 3 dimensional tetragon shape is formed. Difficult enough as that is, the balls can be detached from each other and then attempt to reform the tetra by re-attaching. This last way of solving may seem easier, but is much difficult as  the balls must be connected in just the right sequence. Probably the most difficult 3-D puzzle anywhere.

 

BUCKYBALL

Not difficult--but involved--meditative, and an ornamental work of art.

$35.00

The completed puzzle is a model of the Carbon (C60) molecule commonly referred to as a Buckyball (definition: a ball-shaped hollow sphere made of 60 carbon atoms located at the corners of the polyhedral structure consisting of pentagons and hexagons).

Carbon is an incredible element and the key ingredient for most life on Earth. Arrange carbon atoms in one way, and they become soft, pliable graphite. Re-jigger the arrangement, and the atoms form diamond, one of the hardest materials in the world. In 1985 a new form of carbon was found-- scientists created a mysterious new molecule made of pure carbon. This molecule turned out to be a ball-shaped hollow sphere made of 60 carbon atoms located at the corners of the polyhedral structure consisting of pentagons and hexagons. It was named the buckminsterfullerene after the architect who designed geodesic domes. The molecule, resembling the shape of a Soccer ball, is now more commonly known as the "buckyball"
