Pour the water into a microwaveable container.
Place the macaroni (1/3 the amount of water) straight into the container from the package. (Make sure they are completely covered with water.)
Microwave for 6 minutes at 600 W, uncovered.
Quickly cover the macaroni with a lid and let it sit for 6 minutes. Then it's done. (It will have a somewhat stiff texture.)
Drain the macaroni in a colander and let sit. It will become a little softer after sitting in the residual heat. If you soak the noodles in water and then drain, they will turn out a little stiffer.
