Our friend is incredibly creative - including creating jewelry. You know, she told us about how she made a beautiful gold ring. Actually the ring is designed in wax. When she has the ring design that she wants carved in the wax, she pours plaster-of-Paris around that molded wax ring. Then she puts it in an oven. Well, of course, the intense heat melts the wax away until there's no wax left, just a vacuum, which is shaped like the ring she wants. Then she puts this in a centrifuge, and that spins gold into the vacuum where the wax used to be. Gold rushes in where it used to be just wax. And out comes something very beautiful and a whole lot more valuable.
