Hard Boiled Eggs
Don’t let Pinterest fool you: If you try to hard boil eggs in your microwave you’re likely to either end up with a big mess or burned fingers! The rapid heat from the microwaves creates a lot of steam in the egg, which has nowhere to escape. An exploded egg is hard to clean up
Not only does microwaving frozen breast milk warm it unevenly, which can create scalding hot spots for sensitive little mouths, but other research has also found that this heating method may destroy some of breast milk’s immune-boosting proteins, particularly on high power. A better bet: Nuke a mug of water, then place a bottle of breast milk in the mug to come to room temperature.
Chinese Takeout Containers
Metal (even small amounts of metal, like the handles on those white containers) and microwaves don’t mix. Or, more accurately, when they mix, they can start fires. Put the rice in a bowl to warm it up.
You know you shouldn’t pop plastic leftover containers in there, but you still do. Here’s why that’s bad: Many plastics contain estrogen-like chemicals (BPA is a well-known one) that can leach into your food when the plastic is heated. In a study published in Environmental Health Perspectives, 95 percent of 450 plastic products (such as baby bottles, zipper-top bags and containers) tested released chemicals that acted like estrogen after they were microwaved, washed in a dishwasher, or soaked in water. Even products labeled ‘BPA-free’ released estrogen-like chemicals. Better to be safe and warm up your dinner directly on a plate
With no food or liquid to absorb the microwaves, the magnetron (which is what makes the microwave function) ends up absorbing the microwaves instead, which can damage your microwave and even start a fire, according to the USDA. Make sure you don’t accidentally press ‘start’ without food or drink inside.
