Tina,Let me reply with this:So what you are trying to get us to bvieele is that men had to be trained to stop harassing females in the workplace?What a joke in itself.And your comment: When I got out of college, almost every man in the office harassed every female in the offices I worked in. It was standard practice. Not sure where you worked, but I find this comment hard to bvieele. EVERY female was harassed?Standard practice?And how can pictures of women in bikini’s be considered harassment ? If you take your reasoning to it’s farthest degree, if someone who had a picture of their house on their desk, and it was a mansion, and I lived in a trailer, I could consider the picture of the mansion harassment because my house doesn’t look like the one in the picture.It’s ridiculous to think that a picture can be considered harassment. I don’t care what the picture consists of, if you don’t want to look at it, don’t look at it. Your reasoning is IF ONE person finds something offensive, then it’s offensive. It’s my view that people should be MORE tolerant of others and NOT less as you suggest.It seems to me that you are looking for everyone to think and act alike.Indoctrination comes to mind.Tina, I have to comment that you are NO conservative.In no way, shape, matter or form would I consider your beliefs to be the way a conservative thinks.Now go on and tell me about how you bvieele that you have to bvieele in the bible, think that smoking, drinking, doing drugs, looking at porn and who knows what the next vice they will come up with that is wrong (maybe soda will be next, or maybe if you eat a McDonalds) before you are a conservative.To me conservative is simply a term to determine how a Country should handle it’s business.And in my opinion, the Country’s business IS NOT telling people who they worship, what they do to their own bodies, or what the look at.Those are ALL LIBERAL points.I want to make it clear that I don’t mean to be so critical of your comments, but I do feel it is necessary to try to get YOU to understand that the MAJORITY of people bvieele as I do, and as long as you are for being restrictive of how INDIVIDUALS conduct themselves, then you are NOT conservative.ANY time you restirct something, it is a LIBERAL point, NOT a conservaitve point.No book banning, no behavior restrictions, no regulations and no indoctrination.ALL of these are LIBERAL points, in my opinion.

Penn and Teller are right (mostly). You can’t really “fool” the lie detector, but you can make the test inconclusive, by just clenching your arse. It drives your blood pressure up, thus invalidating the test.

Unfortunately, that’s why they started giving lie detector tests with the subject sitting in a chair where they were reclined at an angle where it is not possible to clench your arse tight enough.

The Civil War steam powered machine gun still exists. It is rusty, covered with bird dung, and the steam engine is missing.However, it is still some what intact. I have about 10 JPG photos that I have taken of it. If you are interested please send me your e-mail address and I will send them to you

If I wanted to beat a polygraph I would use a lawyer and a scientist. The reason is that there is absolutely no convincing scientific evidence that polygraphs are worth a rat’s ass. The Soviet spy Abell beat polygraphs several times.
In an emergency I once replaced a fuse with tinfoil. Very dumb and dangerous thing to do. However, I don’t think you would need much current to cause the tinfoil to fail.

I love Mythbusters, but there does seem to be one thing lacking. If they did some basic internet research after getting their results, they might well find they are wrong in some cases or there is other research that impacts on their results.

Here’s the way to beat a lie detector, believe your lie. I’d like to see what would have happened if they had believe they were given the money by the envelope they read, instead of took, or stole that money. It’s a iteration of the truth really, and it’s all a matter of perception. And criminal minds can be convinced they did something right…

Everybody is talking about the length of the barrel needing to be longer. That, would make the gun more deadly…… I mean we could make it 3 feet long and end up more with quite a velocity, but the Mythbusters were sticking to the original Confederate plan. I do see a problem with the design though. The drop of the ball needs to be timed correctly. If the ball is tossed in and makes it’s way to the “protective shield” on the outside, it will contact the shield sending the ball back into the barrel and then out, losing much velocity or roll along the shield to the point of exit losing any of the acceleration that the projectile would have gained in rolling down the barrel. Think about how much energy was wasted when the ball was denting that shield. The only thing that throwing multiple balls down at once was accomplish allowing a sacrificial ball to hit the shield, but the other projectiles were still right behind it and had already lost acceleration.

It appeared that the geared device that Adam was working on was for this purpose, but it was not adjusted correctly. It Should work similar to a WWII aircraft machine gun connected to the crankshaft that times it just right as to allow the bullet to fire between the propeller blades and not hit one.

Oh! By the way, did Kari and Tory really took a bus back to San Francisco?

Hey, the projectile in the steam gun is not pushed by the steam pressure, so the bullet in the barrel don’t have to be tightly fit. But as mentioned by others, maybe you can lengthen the barrel, or use the lead ball.

Was the myth on the steam gun that they successfully built one or that it was leathal?

I have discovered the fault in the Steam Machine Gun. The muzzle was too short and the projectile release mechanism (PRM) was…well…nonexistant. First, the muzzle should be extended to 2.5 feet, with the PRM no more than six inches from center of muzzle rotation. Now for the PRM. At 2000 rpm the rotational period is .03 seconds. Thus the PRM needs to load each projectile within that amount of time. Once released, the projectile experiences accelleration forces due to spinning. This starts at 22000 g’s at six inches, and ends up at 131000 g’s at the exit end. The average accelleration is 88000 g’s, resulting in an exit velocity of 468 fps. This copares favorably with slower .22 caliber and much better with the 250 fps test result. Double the muzzle lenth gets 700+ fps. Double the RPM’s gets 800+ fps, but shortens the cycle time unless you use more than one cycle to fire (so, if you use a two cycle fire sequence, the cycle time is unchanged).

RPM’s that work this quickly are well within the technology of the mid 1800′s. It may seem that the original blueprints may not have included this mechanism, remember that even Leonardo’s plans were filled with errors to preserve “intellectual rights” and so the plans you saw may have been deliberately omitting this detail for that reason.
