Gorilla snot. At my store we use that term to describe 3/M Super Weatherstrip Adhesive, due to its yellow snotty looking appearance, and its ability to stick to damn near anything. When that stuff hardens, not only does it require a wire wheel to remove, but it looks like. . . yep, dried up gorilla snot. LOLLLL

Thats what I found out when I started searching the web for it. I knew it was 3M but never questioned it being called anything beside Gorilla Snot or fender grease, or fendr fluid. Maybe thats whay it's so dang good on weather stripping too...LOL
I put a 72 Corvette together with that crap 10 years ago or so. It's dang good stuff!


PS You DO NOT.... want to get it on your hands or any good clothes! Been there done that, not good!

 

I'd hate to hear what your idea of bad, low paying jobs is.

 

OK, I have a good "This guy dosen't have a clue story" It will also please tha gals on the site.

Last fall, I'm at my friends house to help him bring in his firewood for the winter. At aroud 3 PM, his Brother-in-law shows up with his summer tires (Still on rims) that he want's to store in the attic of my friends garage for the winter. So my friend and I start bringing the tires up the ladder since we were in work clothes already when the Brother-in-law (An HVAC Engineer... yes... a real bonified Engineer) says: "OH OH wait a minute, there's 32lbs of air in those tires, I forgot to take the air out, It'll be a lot easier if I take some air out". When my friend (A High school Physics and Chemistry teacher) and I burst out laughing, thinking that he was joking, He insistes, "Oh no, don't laugh, you'd be supprised at how heavy AIR actually is" My friend and I simply looked at each other, and figured it was useless, so we let him take some air out.


NOTE: I do not wish to infer that all engineers are this thick, I just happen to know this one.

I was waiting in line at the local Bank last year when I over heard the conversation of two guys in front of me- one was transfering money in his accounts so he could pick up his new car at the Volkswagon dealership....
"So, your getting the new car today?"

"yep- it came in from Germany last week, but I couldnt pick it up till this week.

"Why the wait? paperwork?"

"Nah, because it was shipped from Germany, they told me they had to swap out the stock radio for an american one- otherwise I'd just get German radio stations... Unfortunetly, it cost me an additional 300 bucks..."

At this point I burst out laughing, and the two of them shot me a "whats so damn funny" look.... I told them I just remembered something funny.

 

Although he worded it poorly, there is a difference between the two radios.
Some radios are capable of operating in both the U.S. and Europe apparently the one in his car wasn't. In Europe the radio frequencies are spaced differently than in the United States. European car radios also use Military time. If a Car Stereo is showing military time then it is probably set to receive European Radio Frequencies.

Instead of saying he'd just get German radio stations, he should have said it was set to the European frequency.

 

As an engineer myself, I have to point out that air DOES actually weigh something.
At sea level, air weighs 14.7 pounds per square inch. This atmospheric pressure is the weight of the air molecules in a column above it.
If you had a large enough container and weighed it full of air and again with a vacuum apllied to it, there would be a difference.

Of course, refering back to your original story, the weight of air in tires is so small as to be non existant (due to the volume) but your buddy was technically correct.

Air has weight. (or I should say, Mass)

 

EnglishAdam, Yes, You are right that air does infact have a mass, and we did calculate it out for the fun of it after the brother-in-law left, I can't remember exactly but I think an average 15in Tire at 30 PSI had about 0.009 grams of air in it or something in that ball park. Hardly engough to make a Difference

I hate to say it, but theres idiots for any problem, and someones laughing about someone else all the time. Like me, I know quite a bit about trucks, can do most of the work myself. Take my to a liquor store and I'm looking for the wine with the prettiest label or the nicest looking bottle, I have absolutely no clue. So liquor store owner is laughing his *** off about me.
Granted since cars are one thing we use every day, more people should know more about them, but hey, every profession has its moron customers .
Just think of some of the computer questions I get from my parents... LOL.

 

So you're saying we don't use booze every day? I take offense...

 

Vacuum is otherwise known as the absence of air..... why do you think you cant just purge your A/C system and refill it? It has to have vacuum, which is lack of air, so that when the new stuff is added to it, it sucks it in and there is no air inside the system which could cause faulty A/C. Same as outer space, the reason vacuum is there, is because there is no air in space....so when an environment that holds air is put into space, and a breach is made in the integrity of it... the lack of air (or vacuum) pulls the air from inside the object.... kinda like when you drink a platic bottle of coke, and start sucking on it... you pull all the air out, and when you let go... the vacuum pulls it back in.


as for air having a weight? yes it does... but not in reference to POUNDS of it... i dont think anyone will ever see a POUND of air... it is VERY lightweight, which is why all the air in our atmosphere doesnty crush everything underneath it... think about it... the only time air is destructive is under high pressure, or geographical force (storms, etc...) but stick a tire and rim on a scientific scale, and air it up to max pressure.... see what the change (if any) is...

 

Not quite. Actually, a vacuum is defined as an absence of pressure, not an absence of air.

While there isn't enough "air" in outer space to support our bodily breathing functions, there is "air" in space.

As far as a vacuum sucking or pulling the air out of an object (Coke bottle, space ship, etc.) that is not an accurate description either. A common but incorrect belief is that a vacuum causes “suction.” Actually the apparent suction caused by a vacuum is the pressure of the atmosphere tending to rush in and fill the unoccupied space. The gases ("air") in a space ship are under pressure (1 atmosphere or so) to simulate the Earth's atmospheric pressure. That is what our body needs to have exerted on it to keep our internals internal. If a breach occurs in the hull of the space ship, the air pressure forces the inside air out into the lower pressure outside. This continues until the pressure inside is the same as the pressure outside. Space does not "suck" the air out of the space ship...

As far as the Coke bottle goes, the atmospheric pressure around you forces air into the bottle; the partial vacuum you created by sucking on the bottle does not "suck" the air into itself.

Actually, if you were to get in a lake or ocean and dive down to 10.3 meters, you would have the same "weight" or pressure, per square inch, on your body, as it does when you are at sea level on dry land. In effect, the entire atmosphere of the Earth exerts the same pressure on you as roughly 33 feet of water does in a lake or ocean.

No flame intended...

 

Good follow-up B, but there is one minor problem w/ your 33 feet of water correlation...

At 33.9 feet below the water surface in a lake or ocean, you would have 2x the pressure exerted on your body as if you were standing at sea level on dry land (14.7 psig + 14.7 psia). You forgot to include the weight of the air column above the water level...now had you said it was 33.9 feet of water in a vacuum...then that would be a different story.

8 pound vacuum...

 

Watch this......

What is (+) vaccum?

There is 1 true answer and a 2nd smart **** answer!

Hint to 1st:
HVAC engineers use it especially during the design phase of a system.

Hint to second:
Sarcastic opposites.
