I purchased 2 tons of corn yesterday and happily loaded it into the hopper and disappeared for work. Upon return my entire house smells like rotting eggs, and it's coming from the heat vents. How does corn smell similar to rotting eggs and is this a health threat? What is the best way to camouflage the smell?
Answers:    You have a see all right. You shouldn't smell anything. Sounds close to something died in your vent, not surrounded by the fuel.
