If "some" is large enough, drop the bottles in 1-foot increments up to N all at the same time. Or at least use your dual hands in parallel.

From Half the distance(N/2) drop a bottle,
If breaks (Drop the bottle at N/4 i.,e going downwards)
If Does not Break( Drop the bottle at N/2+N/4 = 3N/4 i., going upwards )
This way you should be able to find the max height where a bottle breaks.
