Re: [Phys-l] ingenious? or just perverse?

This 'Savage' method seems rather symmetric to me.
How does the added 'top' differ from the existing 'bottom'.

I'm missing something here.

Meanwhile, the Adam Savage scheme appears to be the following: start
with a five-faced object consisting of a cube that is missing its top.
Crease each of the four side-faces along the diagonal from northwest
to southeast. This is a "valley" crease as seen from outside. Then
collapse the cube with a twisting motion. It works fine for the five
faced object ... which is what they proudly showed on the TV show ...
but if you try it with the sixth face in place it doesn't work nearly
so well.
