You don’t need a fancy coffee machine to make a single cup of coffee with the Rocket Fuel Pour-Over Coffee Brewer. Simply insert a standard #2 coffee filter in the “red rocket-themed contraption”, add coffee grounds, and set it on top of your favorite coffee cup. Pour in the hot water, and you’ll have a steaming cup of coffee in no time. You can use it at home, at the office, or anywhere you can get some hot water. The Rocket Fuel is $9.99 at Perpetual Kid.
