Brilliant chemistry hack  JUN 13 2002

When Germany invaded Denmark at the beginning of World War II, exporting gold became a crime. Niels Bohr, entrusted with the Nobel Prize medals of Max von Laue and James Franck, didn't want those gold medals to fall into German hands or risk smuggling them out of the country. He and a colleague hid the medals for the duration of the war by dissolving them in acid, each medal in its own jar. When the war ended, the gold was recovered from solution and recast by the Nobel Foundation. (from The Making of the Atomic Bomb)
