Drop the first one at floor 50. If it does break start with the second egg at floor 1 and work up from there until it breaks. If it doesn't break take the first egg and drop it from floor 75. If it does break take the second egg and start working upwards from floor 51 until it breaks. If it doesn't break drop the first egg from floor 88. If it breaks from Floor 88 take the second egg and drop it from floor 76 and work up from there until it breaks. If the first egg doesn't break from floor 88, take it up to floor 94 and drop it from there. If it breaks take the second egg and drop it from floor 89 and work up from there until it breaks. If it doesn't break take the first egg and drop it from floor 97....no, chances are it will be good for floor 100 and go from there :)
