| Dr
Percy Spencer got the idea for a microwave oven when a
candy bar in his pocket melted while he was standing next
to a vacuum tube called a magnetron. The first
commercial microwave oven, made by Raytheon Corp in 1947
was 1.6m tall, weighed 340kg and cost US$5,000 Microwaves become common in Western
households only in the 1980s.
Who
would have thought that an accident in the lab would
result in an invention that redefined cooking? These
rectangular boxes that cook without using heat are now
ubiquitous in most homes.
Microwave
ovens have spawned a whole range of supermarket
foods--everything from pizzas to popcorn are now
microwaveable. Even the most complicated dishes can be
prepared in an instant, thanks to the microwave oven.
