1934 - The metal beverage can is invented (American Can Co., United States)

1940 - April - 1st electron microscope demonstrated (RCA), Philadelphia, Pennsylvania, USA

The microwave oven was invented accidentally in 1945 by Percy Spencer, a Raytheon engineer. While testing a magnetron, he noticed microwaves melted a candy bar in his pocket. Experimenting further, he discovered microwaves could cook food quickly. Raytheon patented the process, and by 1947, they built the first commercial microwave oven, called the 'Radarange.' Initially used in commercial settings, microwaves becomes affordable for home use by the 1960s and 1970s, revolutionizing cooking.
