The microwave has been an integral part of the home kitchen for over half a century, and yet we're constantly told it emits radiation, makes food unhealthy and cooking anything covered in foil can start a fire.
But we've all knows somebody who stands right in front of the microwave oven while they're food cooks or sticks tin foil covered dishes in the micro and doesn't even bat an eyelash as sparks fly inside the machine. So what's the real deal?
Truth is foil is fine in the microwave as long as it covers less than 1/4 of the food, and as long as the sheet is kept flat it won't spark, since the sparks are caused by the crinkles in the foil.
And this video by Reaction debunks the theory that microwaved food is less healthy, and explains why microwaving is actually "one of the best ways to maintain nutritional value in food".
