I'm sure it wasn't a great idea but we used to microwave things for the effect. At one point there were no lightbulbs left in our house because they'd all gone in the microwave. Your very own Aurora Microwavas from the comfort of your own kitchen.
Eventually the gas in the bulb expands too much and the bulb itself shatters. In my experience, other than having to clean up the broken glass, the microwave still runs fine. At one point we had a bulb where the glass expanded out enough to ease the pressure created. We could use it again and again.
Maybe it's a bad thing to do, maybe there's some horrific gas that's created. Someone on here could weigh in on that. It's an incredible effect though and I'd happily do it again.
Obviously, general disclaimers on looking after your own health and safety apply.
Energy-saving light bulbs are so dangerous that everyone must leave the room for at least 15 minutes if one falls to the floor and breaks, a Government department warned yesterday.
The startling alert came as health experts also warned that toxic
mercury inside the bulbs can aggravate a range of problems including migraines and dizziness.
And a leading dermatologist said tens of thousands of people with skin complaints will find it hard to tolerate being near the bulbs as they cause
conditions such as eczema to flare up.
The Department for Environment warned shards of glass from broken bulbs should not be vacuumed up but instead swept away by someone wearing rubber gloves to protect them from the bulb's mercury content.
In addition, it said care should be taken not to inhale any dust and the broken pieces should be put in a sealed plastic bag for disposal at a council dump not a normal household bin.
None of this advice, however, is printed on the packaging the new-style bulbs are sold in. There are also worries over how the bulbs will be disposed of.
Good shout, thanks for the link. I'm not sure the effect would really work with energy saving bulbs so there's no point using them anyway. Thanks for pointing out the risk.
Would be good to find another source other than the daily mail since they're scare mongering racists. They probably give the same advice about immigrants. (If there's one in the room take your family and leave for 15 minutes)
That was the first link I found btw. There are other links like the following from the Environmental Protection Agency http://www2.epa.gov/cfl/cleaning-broken-cfl
if you think there is something with the validity of the article linked previously. It raises the same issues.
Furthermore, the discussion was not specifying incandescent, but I specified energy saving just in case.
Microwaves interact with metal in interesting ways. It will likely induce high voltages in the computer's wiring, causing the chips to release all of their magic smoke.
I grew up in a time when microwave ovens were first released. As such the very first thing you learned is no metal in the microwave oven.
I'm wondering if people who are younger somehow think of this differently or aren't automatically taught the same thing. I mean it seems so obvious (to me) that I wouldn't even think to point it out to someone actually. It's like saying "don't let the car run over you" or "don't play catch with the laptop".
This is entirely not true.
When microwaves were first released, they were so low powered that microwave cookbooks gave advice like "wrap the edges of the chickin in foil".
I don't think "most" microwaves have a metal rack, although they're not uncommon.
It's also not uncommon to see microwave-safe food containers that contain metal. I've seen grocery store deli soups, for example, that end up with a big ring of metal around the top when you open them, but can still be microwaved.
Still, "no metal" is a good approximation. "Unless it says you can use it" is probably OK to leave implied.
I've seen that as well. I'm wondering (from my own experiment) if it has something to do with angles vs. no angles [1] in terms of the metal in addition to the blocking by metal of the actual microwaves.
[1] Same as with stealth airplanes avoiding radar, right?
"Came out" refers to when they became in widespread use. That was in the 70's.
As far as low power I can find nothing that indicates that it was ever ok to put tin foil in however I do know that in some cases you might put metal to specifically block cooking. So perhaps with a low power microwave there was no sparking etc. (I can't find anything on that and I don't see the link you sent showing that (which page is it on in the cookbook?).
A regular oven provides heat from a heating element (which may be gas, electric, wood fuel etc), which heats the air in the oven. A microwave provides heat by using radiowaves to agitate responsive molecules (water is one) in the food - any warmth you feel when opening a microwave has come from heating the food, not the microwave itself.
When metal is in a microwave, the radiowaves hitting the metal create sparks, and sparks kill electronics.
