I have plenty of incandescents for the rest of my teaching career. Very
useful tools. I also break a large one open and put in series with a small
one. Blow of the filament of the larger one to see what happens to the
brightness of the smaller one. Great activity ("Sensitive Filament") from
Square Wheels (Exploratorium Science Snackbook).
