There was a time when the microwave felt like magic. Toss it in, hit a button, and voilà—hot food (or at least something warm-ish and steaming). But as it turns out, not everything was meant to face the heat of those humming coils.
From metal mishaps to eggsplosions, the microwave has seen its fair share of questionable guests. If you’ve ever stood there wondering, “Can I microwave this?”—well, these 15 items are here to tell you: probably not.
15. Foil-Wrapped Leftovers
Aluminum foil might work in the oven, but in a microwave, it’s a fireworks show waiting to happen. Sparks fly, literally, and not in the romantic way.
14. Hard-Boiled Eggs
Trying to reheat a hard-boiled egg in the microwave was a gamble no one won. One second, it looked fine; the next, it exploded in a mini food grenade.
13. Metal Utensils
Someone always forgot to take the spoon out of the mug. Cue the sparks, panic, and rapid door-flinging open.
12. Grapes
Yes, people tried microwaving grapes—and they turned into tiny plasma fireballs. Science experiment? Maybe. Snack? Not.
11. Plastic Takeout Containers
Microwaving the leftover lo mein in its original container seemed convenient until the plastic warped, and the smell of regret filled the kitchen. Not to mention the potential for mystery chemicals.
10. Nothing at All
Microwaving an empty microwave is the ultimate “don’t do it” move. It can damage the machine faster than you can say “popcorn.”
9. Travel Mugs
That insulated stainless-steel mug isn’t just keeping your drink hot—it’s reflecting all that microwave energy right back where it shouldn’t. And your coffee? Still cold.
8. Sponges
The internet told us microwaving sponges killed germs. What they forgot to mention was the smell, the smoke, and the lingering sense of doom.
7. Sauce Packets
Those tiny fast-food ketchup or soy sauce packets seemed harmless—until they started puffing up like a balloon at a clown convention. And then, of course, they burst.
6. Styrofoam Cups
Nothing says “I made a mistake” like drinking coffee that now tastes vaguely like melted foam. Bonus points for having to clean the sludge off the rotating plate.
5. Hot Peppers
Throwing hot peppers in the microwave is the easiest way to gas everyone out of the kitchen. The spicy steam is brutal and unforgiving.
4. CDs and DVDs
Sure, it looked cool for a second, like your own private lightning storm. Then it smelled like burnt plastic and poor life choices.
3. Brown Paper Bags
Trying to DIY popcorn in a lunch sack seemed like a good idea… until the whole thing caught fire. It turns out that brown paper isn’t microwave-safe after all.

2. Whole Fruit
Bananas, oranges, apples—if it was round and fruity, someone probably tried nuking it. The results? A juicy, oozing mess or a mini explosion.

1. Tin Cans
Microwaving an actual tin can is like asking your appliance to self-destruct. It’s loud, it’s dangerous, and it’s peak chaos-in-the-kitchen energy.
