Radiation therapy employs extremely high-powered x-rays, particles, or radioactive seeds to destroy cancer cells. Steel wool and vinegar can be used to teach students about heat transfer as well as endothermic reactions. Capturing footage at 2,900 frames per second, the scientists watched as just 34 percent of the kernels would pop at 170 degrees Celsius, but once the temperature hit 180 degrees, they all went crazy - 96 percent of them forced their fluffy white guts out of their golden hulls like good popcorns. The flavor of radiation-popped popcorn is also different from other types of popcorn. This type of popcorn is said to be very dangerous and should not be consumed. When popcorn is exposed to radiation, the kernels absorb the energy and heat up. The soft starch is surrounded by the kernel's hard outer surface. Its a good idea to open the bag slowly because the steam will be very hot. Use the oven mitts when you take them out. Make sure to let the oil in the pot cool down before you add any water to it. In radiation, electromagnetic waves carry energy from one place to another.

Some units may require this precautionary measure, so read your owners manual to determine whether this is necessary. Once youve chosen Popcorn, use the up and down arrows to select the type and size of the popcorn. The heat from the stovetop or microwave heats the air around the kernels.

Therefore, less pressure is built up inside the kernel, which makes it either not pop at all or reduces the flake size after popping. Why does it do that? Because the microwave does not use hot air to cook food, using a convection microwave will not result in a good result for popcorn. When heated, the water inside the kernel turns to steam and builds up pressure.
