NPR's Robert Krulwich does it again: He clues us in to a way-cool video showing how a Japanese artist took a pool of oil (or something like it) and created a beautiful Christmas tree (or something like it). As Robert writes, "I imagine Neiman Marcus, the big Dallas-based department store, might want to try a Texas-sized version, suitable for oil barons with big living rooms."
We start with a pool of oil. We turn on a magnet. The oil travels up a superstructure and blossoms into a tree. Turn off the magnet, the branches, the needles, the tree melt away. It's a puddle again. The perfect tree for an oil billionaire, no?
