Do not try this at home unless you are a certified physics teacher. Try not to think about what all the crap is in this guy’s microwave. And do wear goggles. The really interesting part is after five minutes. That’s where the science starts.

    First a heat lamp in the microwave, now this. Am I seeing a new series here?

    What does this have to do with IPTables? ;)

    Well. Glass, bottles, tables, laden. Duh?

    “…certified physics teacher.”

    Certified? In what respect?

    It’s good to see that Bill Beatty is still around. I learned how to hand-draw holograms from his site, years ago. I should stop by http://www.eskimo.com/~billb/ and see what else he’s come up with lately.

    Hm. I’ve got a microwave oven in the lab that I’ve been using for reducing iron oxides and melting metal – let’s see how the glass works. . .

    Update: I have confirmed that you don’t need a blowtorch. If you can get hold of some magnetite powder (Fe3O4), it will come to a nice red heat in a microwave, and if there is some glass in contact with it, the glass will “ignite” and melt.

    And Now You Know.

    Not only physicists, but chemists too play with microwaves. They are an excellent way to speed up certain reactions.

    Organic chemistry is a little dangerous to perform in a conventional microwave though. The labs that started playing with them had daily explosions. Now well-equipped labs have specially built monomode microwaves which perform reactions in blast-shielded cavities. They still have frequent explosions, but it’s far less messy.

    I played with both – the conventional as well as the expensive machine. When I was using the food microwave I used a plexiglass blast shield and didn’t stay in front.

    Certifiable.

    Ooo, traffic spike! I really should get off my butt and turn more of Unwise Microwave page into “instructional videos.”

    Yes, goggles are a good idea, mostly for when torching the bottle. The glass also cracks when cooling, and sometimes shards are flung outwards a few inches. Keep the oven shut for at least five minutes. If it doesn’t crack, open the door a little, then reach in with a screwdriver or spoon handle and carefully tap the distorted glass to get it started.

    “Too hot to touch,” no it isn’t, not usually The cold glass stays cold, and you can impress everyone by picking up the glowing orange beer bottle. But this time I let it run twice as long (waiting for more plasma.) It wasn’t too hot to touch, but was definitely too hot to grab and lift.

    Amazing. It is hard to believe that you can do it so easy.
