Puzzle #8: Egg on the floor

There is a 100 floor building. You need to do an experiment to find out the highest floor number from which the egg won’t break on dropping.

You are given two eggs that are identical in all ways and you need to use only these two eggs to find out the highest floor number.

If on dropping the egg, it doesn’t break- you can use it again to experiment. (And of course, you can’t reuse if it breaks)

What is the least number of experiments are required to find out the maximum floor number from which egg won’t break?
