I found several marbles that children had lost sixty or seventy years ago, and they were as colorful and bright as the summer afternoon they were misplaced. In the past twenty years, friends and I have placed Planets in exotic and mundane locations all over the Earth. To find one, you just have to start looking. The Glasswork of Josh Simpson Planets have been tossed into volcanoes in Hawaii and New Zealand. Josh has put them in the flower pots that line the streets of Greenfield, Massachusetts, and recently placed one inside the highest turret of the Chambord Castle in the Loire Valley, France.
Planets are in the rain forests of Bali, the fjords of Norway and ruins in Greece.
They are hidden in the city streets of New York, London and Tokyo. Simpson's Planets dot the seven continents and three of the seven seas. Glass is made of silica, one of the Earth's primary constituents. It is chemically stable and will remain unchanged for thousands of years. It cannot harm the environment and is Y2K compatible.
