A remarkable idea occurred to me the other night while watching The =
Learning Channel. What if rotate a hollow metal drum with a bottom on =
it. Rotate it very rapidly such as >300000 rpm or so. The metal must a =
rather high melting point. Next we pour molten aluminum (or some kind of =
metal) into it, and let the centrifugal (or is it centripetal) force =
smash it up to the walls of the drum, such as in a washing machine. The =
spinning action should align the atoms of the metal to be in line with =
each other. As this is spinning about, we let it cool very slowly so as =
not to disturb the arrangement. Once, it cools down to room temp, we =
stop the spinning of the drum, and since the atoms are lined up, light =
should be able to pass through the material cooled into a hollow =
cylindrical shape. Any takers?
