High-temp Superconductors of Silver and Fluorine?
jeffredd writes: "Two researchers at Cornell are predicting high-temperature, nearly resistance free, superconducters made of an exotic combination of silver and fluorine. The main thrust of their theory seems to revolve around the fact that even though fluoroargentates have not been found to have superconducting properties, they are very similar to oxocuprates which set the high-temp record back in 1993. This is for the hard-core physics buffs. You can read the details here"
911 dispatchers in Anoka, Minnesota, received a call from a woman who said she was hanging from her ceiling by a punch bowl. Paramedics learned that she had been polishing the sterling silver bowl with a fluoride toothpaste. Physicists at the University of Minnesota speculate that a thin layer of superconducting material may have formed between the toothpaste and the silver, and that a nearby television set could have induced a magnetic field which caused the bowl to levitate.
