Melt a beer bottle in a microwave

The Unwise Microwave Experiment guy shows how to melt a beer bottle in a microwave oven. You have to prep the bottle by using a blowtorch to make a red hot spot on the bottle.

Stick around for the end of the demo to hear his explanation of how it works.


  1. man, microwaves and glass. I once burnt a marshmallow on a plate for probably between 1 1/2 to 2 hours, and the marshmallow grew gigantic with a charcoal core while the plate had a hole burnt through the bottom. Exciting, but all kinds of dumb

  2. I once microwaved a Pop-Tart for 5 minutes, mainly because I wasn’t paying attention. I mean…how could anything heat up in 5 seconds? Anyhowways, when I discovered my error, it was too late: The Pop-Tart had become a puddle of charcoal, bonded to the plate.

  3. #8: that text appeared when I added the embed code to the post. I couldn’t figure out a way to get rid of it. The WeShow didn’t select anything and I have never heard of the WeShow before until I came across that video.

  4. “Unwise Microwave Experiments” indeed.

    I once had the bright idea of trying to dry out a narrow necked glass vase by heating it in the microwave (the idea was to heat the water in the vase so it would exit as steam). After a minute or two I was surprised to see a glowing spot on the vase. Hmm, didn’t know you could do that – open the door to inspect – put face right in there for a good look – tiny voice in brainstem screams SHUT THE DOOR, MORON! – just as the door closes the vase explodes from the insanely uneven heating. Better to me lucky than smart, I guess.

  5. The physical explanation actually makes sense; but I don’t believe for a second that those engineers forgot the bowl of water for 10 ours in the µhoven by mistake.

  6. Before I watched the video I was originally thinking “Why not call this ‘Melt a beer bottle with a blowtorch’?” but the principle makes sense. I like the plasma!

  7. That’s a famous microwave oven; it’s the same one I’ve been using for ten years worth of “unwise experiments.” And for cooking! It’s still in my kitchen. No real damage, just some charred paint on the chamber ceiling (from plasma blobs.)

    Oh, and the video itself is hosted at metacafe:

  8. @16:

    As any good theist will tell you, that was an angel whispering in your ear. Jeez, you didn’t know that?

  9. angels don’t use that language. Also, the sanctimonious pricks like you to get killed so they can lord it over you in the afterlife.

  10. Awesome video.

    @Hyperkine – Yes. Instead of dried up, crusty debris in the microwave, it’s wet and hot and much easier to clean off.

    You don’t need to ‘microwave boiling water’, just put a mostly full bowl or large pyrex mixing bowl in there and bring it to boil, 5 – 10 min max.
