Microwave Oven (1945)

The development of the microwave oven was one of those happy accidents. American engineer Percy Spencer was working for Raytheon building magnetrons for radar sets when he noticed that a Mr. Goodbar in his pocket started to melt. Spencer realized it had been the microwaves that had done the trick. The first food he deliberately cooked? Popcorn of course.

微波爐（1945年）

微波爐的發明是最巧妙的一起“事故”。當時，美國工程師珀西?斯賓塞正為雷聲公司的雷達裝置制造磁控管，他發現口袋中的巧克力受熱融化。斯賓塞意識到是微波導致的。那么他有意用微波烹飪的第一種食物呢？當然就是爆米花。
