I'm not too math-y, but this did capture my sense of wonder.

However, it was short lived since now I know it takes "14 drops" maximum, but not the solution - "which floors should I use the 14 drops on though?"

Maybe I'd be intrigued enough to try and follow the math if that was added in :)

First the 14th floor, then the (14 + 13 =) 27th floor, and so on.
