When it comes to household questions about what is safe to microwave, the answer often leads to surprising, albeit entertaining ideas. One such notion that has circulated over the years is whether or not you can microwave a penny. This seemingly innocent question raises eyebrows because, unlike food items or typical kitchen utensils, a penny is a small metallic object that falls outside conventional microwaving practices. But what really happens when you put a penny in the microwave? In this comprehensive article, we will explore the science behind microwaving metals, the potential risks involved, and why you should think twice before attempting to microwave a penny.
The Science Behind Microwaves
Before diving into the topic of microwaving a penny, it is essential to understand how microwaves work. Microwaves are a form of electromagnetic radiation made up of waves that generate energy, primarily used for heating food. When you place food inside your microwave, the microwaves excite water molecules in the food, causing them to vibrate and produce heat.
Key Points on Microwave Functionality:
- Microwaves penetrate food to heat it from the inside out.
- They work primarily by exciting water molecules; dry substances heat differently.
This understanding of microwave functionality lays the groundwork for exploring why certain materials, particularly metals, can cause problematic reactions.
Can You Microwave a Penny?
At this point, you might be wondering: can you microwave a penny? Technically, yes, you can place a penny in the microwave. However, the consequences can be quite dire, not only for the penny but also for your microwave and potentially even your home.
What Happens When You Microwave a Penny?
When a penny is placed in the microwave, it can generate interesting, albeit dangerous, effects. The first thing you should know is that pennies are composed of metal, which conducts electricity. This can lead to arcing, where electric arcs cause sparks to fly between the penny and the microwave’s walls, creating a potentially hazardous situation.
Consequences of Microwaving a Penny:
- Sparks and Arcing: This poses a fire risk and can damage the inside of your microwave.
- Damage to the Microwave: The metal can warp or short-circuit the microwave’s components.
The Composition of a Penny
It is essential to consider what a penny is actually made of. In the United States, pennies minted after 1982 are primarily composed of zinc, coated with a thin layer of copper. These materials behave differently when subjected to microwave radiation.
Material Breakdown:
- 95% Zinc, 5% Copper for modern pennies.
- 100% Copper for pre-1982 pennies.
The distinct properties of these metals mean that they interact differently with the microwave’s radiation. For example, copper is a conductive material that may lead to more intense arcing and sparking.
Understanding the Risks: Safety First
While the intrigue of microwaving a penny may seem amusing, the potential consequences warrant serious consideration. Let’s discuss the safety risks involved.

Even if a fire doesn’t occur, microwaving a penny can cause considerable damage to the appliance itself. Sparks can cause the microwave’s inner components to malfunction, resulting in costly repairs or outright replacement.
Dangers of Other Metals
It’s not just pennies; microwaving any metal object can lead to similar risks. Whether it is aluminum foil, forks, or other kitchenware, they can create sparks and lead to damaging incidents.
Alternatives to Microwaving Metal
If you’re eager to experiment with heating items in your microwave, there are plenty of safe alternatives. These include:
- Glass: It heats food well and doesn’t produce sparks.
- Ceramic: Check that it is labeled as microwave-safe to ensure it won’t crack or leach materials.
- Microwave-Safe Plastic: Specifically designed to withstand microwave temperatures without releasing harmful chemicals.
What to Do If You Accidentally Microwave a Penny
If you happen to microwave a penny — or any metal for that matter — and see sparks flying, here’s what you should immediately do:
Turn Off the Microwave
First and foremost, turn off the microwave to stop the flow of electricity. Unplugging the device can also prevent any further damage.
Remove the Penny Carefully
Once you’re sure that the microwave is powered down, you can remove the penny with a pair of tongs while wearing heat-resistant gloves. This will protect your hands from any residual heat.
Inspect the Microwave
Check your microwave for any visible damage. Look for scorch marks, unusual smells, or malfunctions when you attempt to use it again. If you’re uncertain about its safety, it may be best to consult a professional appliance technician.
Why the Curiosity About Microwaving a Penny? Exploring Cultural Myths
The idea of microwaving a penny may sound ridiculous, but it is part and parcel of various cultural myths surrounding kitchen experiments. Videos showcasing the act of microwaving various household items for spectacular results often capitalize on the shock value rather than sound science.
These myths can be fun, but they often gloss over the danger involved. The allure of seeing sparks fly, or witnessing unexpected chemical reactions, gives reason for many to delve into risky behavior without considering the consequences.
The Trend of Viral Microwave Experiments
The advent of social media and platforms like YouTube has led to a surge in videos demonstrating strange and dangerous microwave experiments. Though many are done for entertainment, they put viewers at risk by encouraging reckless experimentation—microwaving coins is a prime example.
