Ratatat

I was singing death metal growls outside for as long and as loud as I can for about 15 seconds. When I was done I started talking regularly to my friends and my voice sounded different for about 20-30 minutes. Am I singing death metal wrong or was I not supposed to do growls really loudly?

No, it indicates damage to your vocal chords. Try hot tea with honey, lemon, and brandy. It will help them heal faster.

Microwaves are made from metal. When metal objects are cooked in it, it explodes.
Why does the microwave not react the same?

First of all, microwave ovens are specially designed to contain the waves of radiation inside themselves. The reason why metal objects inside an oven cause spraks and even explosions is that they act like antennas and absorb the microwaves, and the electric current generated in them produces an electric arc (connected discharge), which makes the sparks. However, the surrounding walls don’t act like an antenna because they don’t have the appropriate shape and they surround the microwaves without being immersed in them. Besides, whatever current it can cause is easily discharged by them into earth.

im planning to have fish and corals but i dont know which bulb should i get for my 150w metal halide light. they have 20k 14k and 6.7 does any body know the difference? which one should i choose.

The difference between these is the color they’ll make the water appear – they produce different wavelenghts of light, which is expressed by different colors. But rather than choosing what looks good to you, you need to choose based on the needs of the corals you’re keeping.

The biggest difference is whether you’re using the metal halide on its own, or in combination with other lighting (particularly actinics, which produce a very deep blue color, like you’re looking underwater at night). If you are using actinics, I’d get the 14K, which is the closest to natural midday lighting in the tropics under about 30 feet of water. If you aren’t using the actinics, I’d get the 20K, as this would simulate the effect of 14K plus actinics.

If you do have the actinics, your coral will benefit by having all your lights on a timer, so you can simulate dawn (1-2 hours of actinic only), midday (actinic + halides), and dusk (1-2 hours of actinic only). It’s a more gradual increase and decrease of light so your fish aren’t spooked, and if you add a few hours of moonlight, you might get natural coral reproduction (release of gametes rather than just dividing).

The place I work at has large metal bins that they want to cover in rust paint before the winter. They plan on doing it in the middle of November, but I was wondering if the paint will apply/dry properly.

should be around 50 degrees. It may not set up well or dry very good. but someone will take the fall for it if it’s still wet 2 weeks later, long as it’s not you. CYA.

I have a metal water bottle at home which I bought about 3 yrs ago, but never used. We are out of plastic water bottles to freeze and I this metal one I have would probably be more conveinient then your average water bottle. Is it safe to freeze?

Thanks in advanced.

Just keep the lid off during the freezing process to allow for expansion of the water freezing.=)

What kind of fluids can I use to remove rust from metal objects in my bathroom? And what kind of scrubbing pad should I use without scratching the metal objects?

Thanks!

I also have heard good stuff about bar keepers friend. You can also try products like CLR. I mention this because i have not seen bar keepers friend in my store.
Additonally i think the type of scrubbing pad you use will depend on the surface you are cleaning. I would worry that any brillo or metal pad would leave scratches. A good rust remover should not need too much scrubbing aid.

I am curious to know what the techno song is called from the fairly newer geico commercials. It is always played when the stack of money with plastic eye balls comes on screen. The tune is rather catchy… haha.

Totally new song?

not sure but LEX is a great song by them!

I have a leak on the inlet to my toilet cistern. I have bought a replacement metal coupling which I connected ok to the mains plastic pipe, but when I connect to the plastic threaded pipe attached to the inlet valve it leaks. What should I usse to prevent the leakage?

PTFE Tape. Like this:

Wrap it around the thread and then screw it in. Try to get it going the right way (with the thread) so that when you screw it on the tape does not unwind.

My friend got me into techno and now i want to know alot of those songs with lots of bass for my big speakers.
