Corn stoves are special stoves that burn dried corn as fuel to create heat.
Think of it like this: You know how you like to cook marshmallows over a fire when you're camping? The corn stove is kind of like a big, indoor fire for grown-ups (with no marshmallows allowed!).
When you put dried corn into the stove, the stove burns it to create heat that can be used to warm up your home. The heat is usually spread around the house through special pipes or vents.
It's kind of like having a magic box that turns corn into warmth! But remember, only grown-ups can use corn stoves safely, so don't touch it!
