The Whirley Pop Metal Gear popper is a great way to start roasting coffee. It combines all metal gears with the aluminum pot to make an economical coffee roaster. Just add some green beans (a thermometer) and your stove and get roasting. Nothing tastes like freshly roasted coffee and it's easy to get a good roast with the popper. Or you could just make some delicious popcorn with it, your choice!
