You were just hired to work at a lightbulb factory as a lightbulb tester. They just invented, they believe, a lightbulb that can resist breaking when dropped from most heights. They have asked you to test their product and find its threshold by dropping the new product out of their 100 floor building. Realizing that this is your first assignment at the company and also that these bulbs are expensive, you will want to test it accurately but not want to waste the product. What is the best way to test this product?

This is a chestnut.
But since no one has jumped in with the answer, I'll give it another life.

Aren't you assuming that there are no defective lightbulbs? Surely not every bulb is made exactly alike (some variance)

also this is not the most efficient way as you may not be done until the 97th floor or something.

Define the word "best", as conserving light bulbs does not seem to be it, despite them being expensive.

Best In the sense of using the fewest amount of bulbs and taking the least amount of time but still getting accurate results.
