Given 20 'destructible' light bulbs (which break at a certain height), and a building with 100 floors, how do you determine the height that the light bulbs break?

There is more than one way to solve this. Please try even if some one else has solved it.

If it's the height from the steet level, just take one bulb and take the elevator up. Wherever it breaks, that's the height.

yeah, another way is to take the stairs instead of the elevator. Laughing

LOL! It breaks when you drop it. Now solve the puzzle from this angle.
