We are using "#47" pilot light bulbs (6.3V,
0.15 Amp).

- When you are done making measurements, we
need to measure the length of the filament.
- Carefully break the bulb, snip off the
filament (with two handles), and stretch it out.

- Because you can still see the sinusoidal
coils, you know that the following filament is not yet fully
stretched.
- Also, this filament broke near each handle
while it was being stretched.
