What it means
The yellow crystals themselves are nearly odorless. What people are actually smelling is hydrogen sulfide, the rotten egg gas, or the organic sulfur compounds in onions and skunk spray. Human noses are extraordinarily sensitive to that family of molecules, which is why a trace of one is added to natural gas so that a leak announces itself.
