What happens if you accidentally put a fork in the microwave?

If the object has pointy bits, like a fork or the metal filigree on a fancy plate, electrons collect at the edges. When enough electrons build up, an arc can jump between the metal and the electromagnetic transmitter. This is what creates that mini lightening show in your microwave!

Could it cause cancer? – SK, Santa Monica, California. The spoon will have essentially no effect at all on the food. Metal left in the microwave oven during cooking will only cause trouble if (a) it is very thin or (b) it has sharp edges or points.

The metal isn’t going to hurt the food in any way, The food should be fine. As long as the microwave seems to function properly, it should be ok, as well. I have accidentally left utensils in the microwave before and the appliance didn’t sustain damage. Damage is just a possibility, not a definite occurrence.

Chances are, you’re not using it as much as you used to. But if there’s one thing we all know it’s that you should never, ever put metal in your microwave. Because It will definitely explode, just like in the clip above from the movie American Hustle.

Spoons contain thick metal throughout, which takes a longer time to heat. The danger associated with metal in the microwave is when a small part of the metal can heat quickly and start a fire. Forks are more dangerous than other utensils when they are placed in the microwave.

While spoons are generally okay, Forks can create sparks due to a built up negative charge in the tines. Depending on what else is in the microwave, the sparks can cause a fire. Even without causing a fire, these sparks can damage the inside of the microwave and make it unsafe to use.

Basically, if you have a piece of metal in the microwave, charges in the metal move around. If there is a part of the metal that is very thin, such as with aluminum foil or a fork, A high voltage could build up that exceeds the breakdown voltage of air and cause a spark.

Boiling a cup of water in a microwave Could cause it to explode. Water could be over-heated (perhaps even past boiling point), as it will just keep on heating up for a long as you’ve set it for. So when it is disturbed or moved, it’s likely that the heat will release by erupting violently.

If the noise your microwave is making sounds like the magnetron except louder, it suggests that A faulty magnetron (or diode – see below) is to blame. A faulty magnetron can also cause an annoying high-pitched sound, which indicates that the magnetron tube is failing due to age and heavy usage.

Microwaving a yellowish banana will turn it brown, which converts the starch into sugar and the banana will taste slightly sweeter. However, the main result is really the banana becoming softer and not all the sugars converting, so use the microwave method sparingly.

You can use materials like Aluminum foil Safely in small quantities as long as your owner’s manual gives the blessing. Make sure the foil is new and smooth, not crumpled.

While the metallic walls that make up the inside of a microwave oven are also made of metal, they are Not likely to present any real danger. Aluminum foil is thin, and when food wrapped in foil starts to heat up, water turns into steam, releasing energy. Because the food is covered with foil, this energy has no outlet.

The fork is the same as it was before you put it in the oven and the food is microwaved. The sparks are more of a fire hazard than a food safety hazard, because they can ignite the food or its container and start a fire.
