You can cook rice easily in the microwave. Just add almost double the amount of water and cook for 6-15 minutes on high power, depending on how much you're making. Remember to use a lid/pierced cling film, and a fairly large bowl, because the water tends to bubble up and make a mess otherwise.

**Edit:** The rice will be hot for a few minutes, so water will evaporate. Hence you don't want it to be dry when you take it out of the microwave, as it will get even drier. Best to take it out when still slightly wet and fluff it up with a spoon/fork/utensil of your choice. If there's still some water left after a couple of minutes, pop it back in for slightly more.
