If anyone on this froum knows about old fashion weapons, like ones that use gunpowder, OR if you know LOTS about gunpowder in general.... please let me know. For school project for younger daughter. :D :D :D
But every gun (modern or not) uses gunpowder. Are you interested only in the old ones?
:oops: that's why it is weapons 101....Quote:

So, can you help me to understand so maybe I can help her to understand? When we google about gunpowder and how it works or how a gun works, we are not really getting much useful information. Probably because we are not correctly phrasing the questions, garbage in...
can ya, will ya or someone else please help us out here? :unknown:
Rockzmom, I don't know if your youngest one has taken any science classes. Either way, she should know that when something burns, it produces hot gases, right?
Well, when gunpowder burns, it produces A LOT of very hot gases and a very high pressure in the limited space between a bullet (or a ball, if it is a cannon) and the closed end of the barrel. And, of course, the gases push the bullet forward — toward and out of the "business end" of the barrel. The pressure is so high that the bullet is accelerated to a very high velocity, so it continues moving even after it has left the barrel and the hot gas no longer pushes it forward. And as the bulled it pushed forward, the barrel (together with lock and stock and the rest of the gun :) ) is pushed in the opposite direction. Since its mass is much greater than that of the bullet, the speed of its motion caused by the gases is much lower.
That's about as simple as I can put it. Please let me know if this explanation has worked for your daugher, and if she has any specific questions.
Okay...now we are getting somewhere!
She gets the part about the gunpowder heating up and causing the bullet to leave the barrel. :good:
Next she wants to know... HOW... does the gunpowder start to burn when you pull the trigger? :unknown:
Depends on the weapon construction. In the old muzzle-loader guns (the ones in which you stuff the powder and bullet down the barrel) which seem to be what she is interested in, the barrel had a small hole near the bottom, called a touch hole. A little bit of powder was placed on the so-called "flash pan" outside the hole. Flash pan is just a fancy name for a small powder receptacle on the outside of the barrel. In the oldest weapons, there was a little piece of burning wicker (technically called a match) attached to the trigger mechanisms. When someone pulled a trigger, the burning "match" contacted the powder in the pan, from which the powder in the barrel was ignited.Quote:

Even later, more variations of the flint-and-steel mechanism were devised; in the latest one, the flint was striking against a piece of steel instead of steel wheel rubbing against the flint. But in all of these varieties, you had a touch hole in the barrel and a powder-filled flash pan on the outside of the barrel. All of the above is about smaller hand-held firearms, such as muskets and pistols.
In cannons, instead of using a complex mechanism attached to the trigger, the cannoneer usually just lit the powder in the touch hole with a piece of burning wicker, usually attached to a long pole.
In modern breechloader firearms, a completely different system is used. Both the powder and the bullet (or a load of shot) are placed inside a metal or cardboard cartridge. A cartridge is often called a round of ammunition or simply a round (if she watches TV, she must have heard the expression). All modern cartridges have a small amount of compressed high explosive substance near their bottom part. The shape of that high explosive (called the primer) and the method of its insertion into the cartridge may differ, but it is always there. Now, when you pull the trigger on a modern firearm, a special mechanism pushes a small device called a striker which punches the cartridge on the outside, causing the primer to explode and ignite the powder in the cartridge.
By the way, rockzmom, have you ever visited http://www.howstuffworks.com?
I found out that I can spend hours on that site.
Here's a portal for your daughter about firearms
http://science.howstuffworks.com/firearms-channel.htm
Here's a whole lot of information about HOW GUNS WORK (from flintstone guns to submachine guns)
http://science.howstuffworks.com/gun-roundup.htm
Ramil.... have you ever heard an almost teenage girl screech with happiness???? You might have heard this one all the way over in Russia my friend!!!
These two graphics from How Stuff Works, made the words from translationsnmru all come together!!!

You guys are the best!!! From her to you!http://i444.photobucket.com/albums/q.../high_five.gif
Her project is not due for a LONG time, so I might need to come back to you guys for follow-up questions, but at least now she has the basics and can start!!!
THANK YOU AGAIN!!!! You ROCK!
You should know that the powder in modern a cartridge is not the same as the powder used in cap and ball muzzle loaders, which use "Black Powder" instead. Black Powder can be bought in any Gun Store in the ammunition segment along with the "percussion caps" to placed on the nipple at the end of the chamber, the cap, replacing the need for a flint. These cap and ball firearms were used at the time of the Civil war, the cartridge not being available at that time.
Watch the video to see how it is loaded. (This is the identical model that I kept in my collection):

You don't need all the gadgets for loading that this guy uses to load one of these. It is not that difficult and can be done much faster. But many people carry a second cylinder already loaded and stored on their belt and just exchange cylinders for fast reloading.

What is the sense of 101? Is it an abbreviation or a phone number, or maybe there is some connection to a fairy tail?Quote:

RUSS298K Soviet Film: Propaganda, Myth, Modernism :spiteful:
Prerequisites: None
CORE course: History/Theory of the Arts (HA)
A survey of Soviet film from the 1920s to 1991, with the main emphases on the 1920s and 1960s. The course focuses on important directors, genres, themes, and styles, beginning with the most internationally famous period of Soviet silent cinema (1925-1930), and continuing through the Stalin period (1929-1953), into the "Thaw" (mid '50s to '60s), the period of "stagnation" under Brezhnev, and finally, "glasnost."
Theoretical issues to be considered include: "propaganda"-- ideology and its integral role in Soviet art, in particular in the overarching rubric of "Socialist Realism," declared as doctrine in 1934; "myth"-- the various myths of the individual, the Russian/Soviet "nation," and history as embodied in Soviet film; and "modernism"-- the structural and technical characteristics of Soviet film art, especially as described by Soviet film theorists.

The second video is GREAT!! She is at school right now but as soon as she gets home I will have her watch it. Thanks DDT... you said "that you kept" as in you no longer have? No guns in Russia right? No one to keep them for you back at where ever you are from???Quote:

I need to go back and fix that!
BTW, she uses a Walther PPK and rides a Ducati 1098s. *)

I am not in Russia right now. I used the past tense because I left this weapon with a person for safe keeping while i travelled. He put it is a vault in his bank with 160 guns from his own collection. He ran into debt with the bank and the bank seized his collection along with mine too, by mistake. A sad story! It was one of my favorite pieces. We used to shoot black powder pistols and muskets most afternoons together back then. Did you notice in the video how much smoke is exuded when shooting with black powder? At night time they make quite a flash.Quote:

I have actually fired a Glock before and I think a .38...it was about 3 years ago and I can't recall. Daughter who is doing said project was also there with me and she did better on the shooting range than I did!Quote:

The other section I was really stuck on was wondering if it was harder to learn how to drive a stick shift car if you already know how to drive a motorcycle. I never really got a clear answer about that one; but, I did learn that in the UK you need to decide before you take your driving test if you are going to do it on a stick or not as that is how the license is issued (for driving a manual car or automatic) and that is not the same here in the U.S.
