Both gallium and indium melt easily at stove-top temperatures, and some of their alloys (perhaps with other components) stay liquid down to room temp and below (I think the lowest has tiny and zinc and is liquid down to 6 C.) I apparently didn't do it all quite right, cause one of my attempts came out more "pastey" than liquid, but it's still neat to play with (not as much fun as mercury; the Gallium indium allows tend to wet most surfaces rather than globing up. But much less poisonous.) BillW -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
