Did you know?
 

Did you know that most tornado sirens are not electronic, and produce sound mechanically via a rotor?

It makes them less vulnerable when they double as nuclear-attack sirens.

It's also cheaper that way.

Did you know ...
On every continent there is a city called Rome.

did you know that the federal thunderbolt was the most popular air raid siren? some of you have probably seen some left over from the cold war. It is yellow in color (sometimes rusted on some spots) and has a long, tapered horn. i think it has the scariest sound i know of. here is a pic of one:

We've got those thunderbolts all over my home town. They use them as tornado sirens now, firing them up for a test minute on the first Saturday of each month. They do shock you when they first start up until you remember that it's a test.

Yeah. The reason they are so scary sounding is that they actually use a supercharger (a real supercharger) driven by an electric motor to force air into the siren mechanism, instead of simply having the rotor pull air in. This results in a louder sound and more of a sonic bite to the sound. The supercharger is located in the large box at the bottom of the pole that is supported on the pole.

Okay, so where's Rome Antarctica? :p

did you know?

It is IMPOSSIBLE to flex your ass muscles (glutes maximus) when you stand, or bend over, and point your heels outward?

[TRY and not smile when you attempt it!]

Did you know it is impossible to draw figure 8s in the air with your right hand and simultaneously move your right foot in clockwise circles?

[Bill]WELL NOW YOU KNOW![/Nye]

TIO: I just did that without error reletively fast
Mr. Sandman: I can do it with my heels outward, but it feels wierd as hell

Xell101:

You must be an anatomical anomaly. It is supposed to be
physiologically impossible. I learned about it when they gave
us shots in each ass cheek prior to going to Nam.

Then an anomaly is I.

(Military service? I thank thee.)

I just did. Are you sure IMPOSSIBLE? Perhaps that word does not mean what you think it means?

Let's see...I didn't mean to start a minor controversy, it's been over 37 years and I don't spend a lot of time doing that anymore.
Maybe it was just if you BEND over (only) and point your heels outward. Anyway I SURE can't do it.
That is how we were instructed to receive the double cheek shots: Bent over a gurney and a Corpsman on each cheek with a HUGE needle. I think it was for the plague.
Maybe got a lot of people trying to squeeze their ass muscles, not a bad thing.

(Of course the whole point of that maneuver was so that we didn't FLEX when they attempted to give us a double injection in our asses!)

A necessary aim. I once snapped the end of a needle clean off by clenching when someone gave me a shot in the rump. That sucked.

thats not true, if u practice and concentrate it is possible!

yup... pissed me off for a few minutes, but I finally got it..... now to annoy my friends with that little game!

btw I can flex my ass while bending over with the heels outward too ;)

Did you know that the male nipple is between 4th and 5th ribs?

Results will vary for females.

Even Antarctica??

I did not know that.

Did you know that the legend of the werewolf and vampire has its origins in a blood disiese called 'Porphiria'? It is a disorder where the heme (iron carrying dohicky in the blood) doesn't exist. The results are becoming hirsuit around the face and hands. The fingures and toes can shrink giving a cloven appearance. It also gives the skin no protection against the sunlight. If they go out only for a few minutes they get heaps of burns and lesions. There gums recede giving the fang like visage. Back in the olden days when there were no blood banks the only way these people could get the heme is to drink blood. 1 in 25000 people suffer from porphyria. 1 in 100000 men have an 8 inche penis. So you have probably met 4 werewolves/vampires for every guy you meet with an 8 inch penis.

Did you know that there are 118 ridges on the edge of a dime?

Lunchbox7: I didn't think Porphyria did that. Eep.

I found out last week how 3D pictures work. You know the ones that if you stare at them a picture comes out of it. The picture is made up of a very complex pattern that is constantly repeated all over the page. Where the picture is the pattern is reversed. As your eyes fatigue the reversal in pattern can be identified and thus a picture emerges.

What if the man has saggy man teets?

Not true. Strong pectorals will sometimes raise the nipples, and excess fat, as rider suggests, may lower it. Some people are simply born different.
Med students are, therefore, always taught to count ribs down to the fourth intercostal space when listening for heart sounds, rather than assume the nipple corresponds to a particular rib.

Lunchbox is being a bit sensationalistic. Although the gene for porphyria is not uncommon, the vast majority of carriers never exhibit symptoms, and the symptoms he describes are very extreme.

re: The_Dude
and
"No, it's not me. I'm a dude."

Did you know?

Our Living Language: Cowboys and the Wild West are indelibly set in the minds of many as typical of America—an association borne out by several common Modern English words that originated in the speech of the 19th-century western United States. One is DUDE, now perhaps most familiar as a slang term with a wide range of uses (including use as an all-purpose interjection for expressing approval: “Dude!”). Originally it was applied to fancy-dressed city folk who went out west on vacation. In this usage it first appears in the 1870s. The origin of the word is not known, but a number of other cowboy terms were borrowed by early settlers from American Spanish. These include buckaroo, corral, lasso, mustang, ranch, rodeo, and stampede. Buckaroo, interestingly, is an example of a word borrowed twice: it is an Americanized form of Spanish vaquero, which also made it into English as vaquero, a cowboy.

(Us old folk, used to say:"Man!")
