Another thing is... umm, every other .50 cal vid I've seen it's hella loud AND the person firing is hanging on for dear life of the kick back. This vid had NEITHER...

If you look at my post again, you see that part of the molecule chain in nitromethane IS nitrous oxide, which carries oxygen into the combustion.

And all the fuel in an engine is vaporized to be as close to a gas as possible. That's what a carb or an injector does. And there's always natural gas engines. . . .



Backwards. The North Star is so called because the North Pole points to it. As for the North Pole not being geographic North. . . It is EXACTLY geographic north. It is the point through which the Earth's axis passes. It's not magnetic North, which is why you get a compass deviation. If, as a navigator, you use the North Star to find North, you will be a trillion times more accurate than using a compass to find North. (Well, maybe not a trillion, but it'll be more accurate.)

My bad... I meant magnetic north... :lol:

Well then it would go THOUGH that material not bounce back, no?

The video's description mentions a solid metal sheet just 100ft away. Should bounce back nicely - ricochets are incredibly unpredictable. There was a story a while ago about a person who tried to shoot the lugnuts off his car's wheels - and the bullet ricocheted into his knee.

.50 are also used on sniper-rifles and have state of the art anti-recoil system. I doubt the US SF would use a sniper-rifle that recoils too hard. And could've been very loud - it's a video where everything else is kinda quiet.
 
Is the movie Philadelphia experiment, based on a true experiment?
 
The 1984 movie's plot synopsis says this: Reportedly based on a true incident during World War II involving an anti-radar or invisibility experiment that caused a US Navy Destroyer Escort to disappear from Philadelphia Harbor. A sailor finds himself thrown into the future (1984).

Wikipedia says this: Operation Ghost was an alleged naval military experiment at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania, sometime around October 28, 1943, in which the U.S. destroyer escort USS Eldridge was to be rendered invisible to human observers for a brief period of time. It is also referred to as Project Rainbow. The story is widely regarded as a hoax. The U.S. Navy maintains that no such experiment occurred, and furthermore, details of the story contradict facts about the Eldridge. It has nonetheless caused ripples in conspiracy theory circles, and elements of the Philadelphia Experiment are featured in other government conspiracy theories.

So once again, Hollywood pulls history lessons out of their ass.
 
Why do our face turns red when we blush and why is it so obvious to everyone?

I don't have the why it happens, but we become red when we blush because of the increased amount of blood near the skin.

It's probably so obvious because it looks different to our usual face - when my friends blush (which is kinda rare, at least with the male ones), I notice it right away since I'm used to their face. And perhaps because blushing usually comes with different facial expressions.
 
This is what I found on wiki about the "blushing area": There is evidence that the blushing region is anatomically different in structure. The facial skin, for example, has more capillary loops per square millimeter and generally more vessels per unit volume than other skin areas. In addition, blood vessels of the cheek are wider in diameter, are nearer the surface, and visibility is less diminished by tissue fluid.

So perhaps when you get embarressed or whatnot, your heartrate increases thus flowing more blood through those vessels and thus making your face red...Course that's just a theory.



Edit: I have a question, why don't they allow the general public into the SEMA show?
 
Because it would destroy some of the press exclusives, and lead to a bit of chaos and horribly out of control flash photography. Thats just part of it, I'm sure.
 
How do I remove Blu-Tac stains from my bedroom wall? I've tried sugarsoap and that ahsn't worked.

Get in good with your local after market/tuning garage. That's what my older brother did, not purposely to go to SEMA, but since he was friends with a lot of guys at the shop they asked if he wanted to go along with them on a company trip to check things out.
 
I can't think of any tuning-type garages around me...oh well, I'll just stick to the custom car shows at the convention center!

How old was this Blu-Tac? Normally it shouldn't. You can try adding moisture to it to soften it up and then peel it off.
Click to expand...

The Blu-tac is off the wall, but it's left a stain. I'm going to try white spirit/methylated spirit later. Got some plastering and filling in my room too. Yay.
 
Oh, I thought you meant that a chunk of it was on the wall.

Is most acne today hormone-induced or a side effect of the chemicals in our environment? These problems seem to be greater with this generation than others.
 
Spots are hormone related. It's never been related to 'dirt'.

I'm a week from being 20, yet am still getting spots (probably at a higher rate than before in all annoying honesty), yet I live in a smallish town, we don't have much of an industry, fresh sea air is abundant. I eat fresh veg, fresh meat, everything is cooked by myself so there are no E-numbers, etc.

Simple - just surround yourself with eight 6'5" Chinese special agents in light blue tracksuits and smack anyone who gets in your way.

Mainly forehead acne. Many Asian teenagers here have it, but their parents apparently did not.

As for the Olympic flame: they don't, or not while it is burning. The fire inside a pressurized aircraft would displace the available oxygen inside and suffocate the passengers. Open aircraft are also often made of highly-flammable materials.

A drone, maybe.
 
I think they just put out the flame on the plane, then relight it once they get to the airport.
 
Or: someone lights a cigarette-

Never mind; smoking is illegal on a plane.

How often does shedding occur for humans? (or, the time an epidermis particle remains on the human body)

The body is always shedding. Skin refreshes itself pretty frequently. I think it was about 8 years for the average skin particle. So you'll be in a "new" skin every 8 years, but some of that skin will probably be about to expire.

How are you going to find that many?

There are tall Chinese. Yao Ming, anyone? The just aren't as common.
 
Hello? Go to a tourist spot in China and you'll be surrounded by 6"+++ guardsmen.

Do they turn off the flame? Don't they carry them in special sealed glass lamps?
 
What are some good race track in Washington state that aren't "leftleftleftleft" every lap? I was planning on going to a trackday with my Uncle and his Viper.
 
or rather your uncle is planning on going and maybe dragging you along
