Polonium-210: the hard-to-detect poison that killed Alexander Litvinenko was also found in Yasser Arafat's body (just a few milligrams of the highly radioactive isotope is a lethal dose). Was Arafat murdered? The jury is still out, according to Poison Queen Deborah Blum writing on her Elemental blog at Wired: " I wouldn’t rule out a poisoning scenario myself; it’s not implausible, given Israel’s ruthless history in dealing with Palestinians and its access to Po-210, that it should be suspected in an assassination plot. But even in the much stronger Litveninko case, there was never what you might call a resolution that included justice."

Orchid: Exploding High-Speed Paint Flowers by Fabian Oefner. "To make the images Oefner poured numerous layers of paint with a top layer of either black or white onto which he dropped a colored sphere. The resulting splash forced the colored paint up and out of the top layer resulting in the crowning splashes of color."
