A pharmacist has 10 bottles of extra-strength Rogaine.  One bottle is
defective having all 6-gram pills.  They are supposed to be 5 grams each.

The pharmacists tells his assistant, George Bailey, to find which bottle is
defective but only to use the weight scale once (He is a really cheap
pharmacist).

The Question: How can George do it.
