Although he was not the first to notice this effect, he was the first to express curiosity for it. He repeated the experiment with popcorns, which became the first food cooked with microwaves - on purpose.
He also tried to microwave an egg, which exploded in the face of one of the experimenters. After that Spencer created the predecessor of a microwave oven by attaching a high density electromagnetic field generator to an enclosed metal box. It blocked escape of microwaves, which allowed for controlled and safe experimentation which Spencer continued with various food items.
All experiments led to conclusion that when a food is placed in the box with the microwave energy, the temperature of the food rises rapidly. Raytheon filed a United States patent application for Spencer's microwave oven on October 8, Wonder What's Next?

Wonderopolis Nov 28, Wonderopolis Nov 12, Wow I did not know that soap can do that in the microwave.
I won't to try it in my house but with a different object maybe tofu. I loved how the soap [ivory] was melting and I can't believe the microwave oven was a mistake. Wonderopolis Nov 10, Wasn't that cool, Kadija?! We learned so much in our microwave Wonder! This video was awesome I can't wait for tomorrow's wonder of the day. What will it be? That was so cool!! A bar of soap! And he didn't mean to. Why did he put a bar of soap in there? I so liked today's wonder!!! Spencer's "Yankee ingenuity" — what Readers' Digest called his "itch to know" — would later help him solve engineering problems that others had either failed to notice or given up on.
Spencer left school in the fifth grade to take a factory job. Four years later, the owners of a local paper mill decided to install electricity. Even though the year-old Percy knew nothing about electricity, he signed on to help install the system.
He learned by trial and error and studied textbooks at night; by the time the project was finished, Percy Spencer was a skilled electrician. The new fields of electricity and wireless technology caught the young man's imagination.
When he learned of the heroic role radio operators had played during the sinking of the Titanic , he joined the Navy so he could learn to be one of them. After he was discharged from the Navy at the end of WWI, the year-old set off to pursue his passionate interest in electricity. About the same time, Lawrence Marshall and Vannevar Bush, who had been roommates at Tufts University in Medford, were also thinking about ways to put electricity to practical use. Thanks to Bush's position on the M.
They decided that electricity could be applied to labor saving devices for the household. In they founded the American Appliance Company in Cambridge; three years later, the company added Percy Spencer to its three-man staff.
One of his earliest contributions was a series of improvements to photoelectric vacuum tubes, a major step in the development of the television tube. In October of , the company's name was changed to Raytheon "rai" from the old French "beam of light" and "theon" from the Greek "from the gods". In it moved from Cambridge to a former button factory in Waltham. From there, it would become one of the world's leading technology firms with employees all over the world. Its early emphasis on household appliances would evolve into a specialization in defense and space electronics.
It was Percy Spencer, with his Yankee way of problem solving, who was responsible for many of the company's biggest breakthroughs. His curiosity was legendary, and he had the ability to collaborate with highly educated physicists while pursuing his characteristic "let's tinker and see" approach.
In , as the U. Working night and day, he increased the efficiency of the magnetron and boosted output from one magnetron a week to an astonishing 2, a day. Radar sets Spencer designed were installed in U. For this accomplishment, he won the Distinguished Public Service Award, the highest honor the Navy bestows on civilians.
