George Bailey and the Extra-Strength Rogaine

The Puzzler

A pharmacist has 10 bottles of extra-strength Rogaine. One bottle is defective. A regular pill weighs 5 grams, while the faulty pills weigh 6 grams each.

The mean old pharmacist tells his assistant, George Bailey, to weigh a pill from each bottle to find the bad batch. But George is in a hurry because he has a date in five minutes. He figures out which bottle is faulty by using the scale only one time. How does he do it?
