Why you shouldn’t use a microwave?
It generates harmful compounds. Microwaves deplete the nutrients found in food. In addition, it replaces the healthy compounds of the dish with radioactive ones. This happens because microwave ovens use microwave ionization to heat up food. Ionization in controlled areas is found to be cancer causing in humans.
How did Percy Spencer create the microwave?
How the microwave was invented by a radar engineer who accidentally cooked a candy bar in his pocket. … One day while working near the magnetrons that produced microwaves, Spencer noticed a peanut butter candy bar in his pocket had begun to melt — shortly after, the microwave oven was born.

When did the microwave became popular?
1967The microwave goes mainstream In 1967, after nearly 20 years of selling the devices to commercial establishments rather than households, Raytheon finally developed something much closer to the countertop model found in kitchens across America today. The first household microwaves were heavily marketed to women.
Why is the microwave important?
Microwave ovens are so quick and efficient because they channel heat energy directly to the molecules (tiny particles) inside food. Microwaves heat food like the sun heats your face—by radiation. A microwave is much like the electromagnetic waves that zap through the air from TV and radio transmitters.
What was life like before the microwave oven?
For anything cooked in the oven, it generally had to be pre-heated. Cooking took a bit longer but, in many cases, tasted better. There were no instant, ready in one minute microwave meals in stores. Popcorn was cooked on the stove in a covered pan or in a plastic kitchen gadget made for popping corn.
How much was a microwave in 1970?
It cost $495 (about $3,200 today). Consumer interest in microwave ovens began to grow. About 40,000 units were sold in the United States in 1970.
What would happen if a microwave was on with the door open?
The microwaves in the oven disappear when the door opens just as quickly as a room gets dark when you turn off the light. The walls of a microwave oven are metal, which keep microwaves inside from leaking out. … The oven’s job is to cook food; a job it would not do very well if its energy were leaking out into the room.

Why was the microwave invented?
As a matter of fact, his name was Percy Spencer and his invention was an accident! Spencer worked for a company named Raytheon, developing microwave radar transmitters during World War II. One day in 1945, he noticed that a candy bar he had in his pocket was starting to melt.
How was the microwave made by mistake?
One day while working near the magnetrons that produced microwaves, Spencer noticed a peanut butter candy bar in his pocket had begun to melt — shortly after, the microwave oven was born.
Is microwave radiation harmful?
Microwaves are just as dangerous as the light emitted from a bulb. … Some research suggests that electromagnetic radiation (every microwave has a radioactive source comparable to an airborne radar) has a carcinogenic effect (can cause cancer) and is mutagenic, it changes the DNA structure of humans.
How did the microwave change the world?
Microwave ovens changed society in a way that it gives us an option to prepare our meals in a convenient and faster way. People sometimes do not have the leisure and time to prepare meals, especially people who work, and having a microwave oven benefits them because they can do it quickly and easily.
