a microwave is one userful thing in my life. It helps me because if I need to warm my food I won't have touse the stove. The  person who created the microwave is Percy LeBaror spencer.  A microwave is a rectangle box with a door that is see-though on one side of the microwave with a panel to work the microwave. It has a botton to open the door and it has a light inside the microwave.
