Each year on December 6th, we honor an appliance that changed the way we use the kitchen forever, the microwave. Self-taught American engineer Percy Spencer was working with active radar in 1945 when he noticed the chocolate bar in his pocket was melting. Spencer realized that the heating effect was perfect for cooking, and two years later, the first microwave was available for purchase. Only 1% of United States households owned microwaves in 1971. That number has grown, over 90% of households today. So, whether it's reheating leftovers, making popcorn, or heating a cup of water for tea, explore the many uses of the microwave oven on National Microwave Oven Day. #MicrowaveOvenDay
