Fun with magnets
I recently borrowed a friends GEOMAG™ set. You get a set of plastic rods with magnets embedded and some ball bearings. This allows you to build interesting stuff! Woo hoo!
A truncated dodecehdron, collapsed.
A pyramid, almost complete.
A stable truncated dodecahedron, using inward pointing supports on each pentagon face.
A six sided tower.

dodecahedron
Did you know what word before you bought the magnets?

Yep. Its one of the regular solids. I learnt it from an Open University show. (Not in school, oddly enough.)
A dodecahdron is made up of 12 pentagons. A "truncated" solid is where the corners have been flattened, in this case with triangles.
