The microwave oven is an appliance found in most modern homes. It is mostly used in the kitchen
for reheating food. It uses microwaves, which are radio waves that heat up molecules inside the food.
It has an automatic shut-off timer which enables food to be heated more evenly, safely and quickly.
At the touch of a few buttons, this device can boil water, reheat leftovers, cook rice and defrost frozen
food in only a few minutes!

The microwave oven was an accidental invention by Percy Spencer. Spencer worked for a
company that developed microwave radar transmitters during World War II. One day in 1945, he
noticed that a chocolate bar in his pocket was beginning to melt. He discovered that the microwaves
from the radar set he was working on were heating the chocolate bar in his pocket! He did some
experiments and figured out that the microwaves could be concentrated to heat food. He created
the first working microwave oven in 1945, and the first food he cooked in it was popcorn. The early
microwave ovens were too large, too heavy and too expensive. It was many years before microwave
ovens were produced and sold cheaply. They were finally introduced to the marketplace in 1967.

Do you know what inventor is? An inventor was someone who comes up with an idea for the first
time. You must be creative hard-working and persistent. You must not be afraid to fail. Instead of
getting discouraged, you must ask yourself what went wrong and try again.

Did you know that Bill Gates experienced many failures before achieveing success? His first
invention, a machine that was supposed to create reports for roadway engineers from raw traffic
data, failed to process the data when he tried to present it to a traffic employee? Yet, he wasn’t
discouraged from trying again. He was able to create a company, that completely changed the
computer industry, and we all know just how successful that was for him.
