The Microwave Oven
I.
First thoughts
What is your understanding of these words:
magnetron, microwave, pop-corn, radar-set.
II. Study the words. Make sure you know them.
bar, snack, kernel, explode, inch
III. Read the text and say why the microwave oven is a big
help to busy men and women.
Shortly after the end of World War II, Percy Spencer,
already known as an electronics and war hero, was touring one
of his laboratories at the Raytheon Company. He stopped
momentarily in front of a magnetron, the power tube that drives
a radar set. Feeling a sudden and strange sensation, Spencer
noticed that the chocolate bar in his pocket had begun to melt.
Spencer, who obtained 120 patents in his lifetime, knew how to
apply his curiosity. So he did what any good inventor would he
went for some popcorn. Spencer didn't feel like having a snack,
he asked for unpopped popcorn. Holding the bag of corn next to
the magnetron, Spencer watched as the kernels exploded into
white morsels.
From this simple experiment, Spencer and Raytheon
developed the microwave oven. The first microwave oven
weighed a hefty 750 pounds and stood five feet, six inches. At
first, it was used exclusively in restaurants, railroad cars and
ocean liners - places where large quantities of food had to be
cooked quickly. But culinary experts quickly noticed the oven's
shortcomings. Meat refused to brown. French fries turned white
and limp. To make matters worse, Raytheon chairman Charles
Adams cook quit because Adams demanded he prepare food
with a microwave oven. In fact, it took decades after the
invention of the microwave oven for it to be refined to a point
where it would be useful to the average consumer. Today,
Percy Spencer's radar boxes melt chocolate and popcorn in
millions of homes around the world.
