- Cooking with metal will make you micowave explode: This is in fact not true, as a matter of fact they are actually constructed of metal. If you put metal in a microwave oven you may see sparks but this will not ruin your oven, although as stated above could start a fire which if gotten out of hand could indeed ruin your microwave.
- You cannot put aluminum foil in a microwave oven: In fact, foil can work to your advantage in a microwave. The metal will inhibit the microwaves and protect that part of your food from being cooked.
- A microwave is a good way to boil water: Not a good idea to boil water or any clear unadulterated liquid in a microwave, the water can heat past the boiling point without displaying boiling action due to a phenomenon called super heating which happens when a liquid heats up faster than vapour bubbles can form. The result is an explosion of super hot liquid when it is moved or something (like say a tea bag or stir stick) lands in the undisturbed water. You may read that this doesn't often happen but this has infact happened to me twice - once with water and once with super hot melted butter.
- Just because I said you can put metal in a microwave don't go putting a tin can in there! It's not the metal that is the problem in this scenario, it' s the closed container - it will explode when the contents heat up and expand, same goes for eggs in the shell and potatoes in their skin that haven't been pierced.
