Microwaving a burrito

When microwaving a burrito, don't place it radially, like the hands of a clock. There are spots in a microwave oven that are cold - the microwaves destructively interfere there. If you put the burrito in the center of the spinning plate and look at the motion of the burrito, you'll see that the part in the center of the plate does not move at all, while the other parts of the burrito follow circular paths at different radii. Different parts of the burrito will get heated differently, some too hot, some cold.

The correct way is to put the burrito on the side of the spinning plate, so that it goes around the microwave like a kid on a carousel. That way, every part on the burrito travels through the same circular path, and it gets heated evenly.
