- Yeah, probably. Nevertheless, if supposedly knowledgable people start

- heed them?

- Powdered Li? That must be pretty reactive indeed. Here at CERN we had
- a chap who played around with Li foil. He worked in a room which had
- two huge dessicators taking turns at drying the air in the room. The
- foil remained clean and shiny. If he took a piece outside
- it would tarnish immediately.
