The electrodes are affixed with small barbs so that they will grab onto an attacker's clothing. When the electrodes are attached, the current travels down the wires into the attacker, stunning him in the same way as a conventional stun gun.

­ The main advantage of this design is that you can stun attackers from a greater distance (typically 15 to 20 feet / 4 to 6 meters). The disadvantage is that you only get one shot -- you have to wind up and re-pack the electrode wires, as well as load a new gas cartridge, each time you fire. Most Taser models also have ordinary stun-gun electrodes, in case the Taser electrodes miss the target.

If I could add a side note; after running several miles of gas pipe in my time, I never used TFE tape on my joints exclusively. I would always use a pipe joint compound/paste type product, Rectorseal was my go-to choice. One day I was in the process of installing one of my gas pipe jobs. It just happened that the local gas supplier tech showed and was checking on something. They supply gas to thousands of homes in our area. He noticed that I was using Rectorseal. He made a point to come over and thank me for using this product. He said that if all the contractors in the area used this product, his job would be a lot easier. So after all this talk about TFE tape, I wouldn't recommend it. It doesn't seal as well as a good quality joint compound.

Some Taser guns have a built in shooter-identification system. When a police officer fires the Taser electrodes, the gun releases dozens of confetti-sized identification tags. These tags tell investigators which gun was fired, at what location. Some Taser guns also have a computer system that records the time and of every shot.

Amnesty International reports that a number of governments routinely use stun weapons to extract confessions from political prisoners. These officials know that electrical torture leaves less evidence than many other methods. The shock from a stun weapon is extremely painful, but it doesn't leave an obvious wound. So, while stun guns might be relatively safe weapons when used correctly, they can be quite dangerous in the wrong hands.

one thing that no one ever mentions is that using too much tape can break a fitting....so the yellow tape since its thicker probably should use less .....Ive broken fittings at times probably because I screwed it too far in and maybe because the tape was wrapped too many times.....if its not screwed in far enough it may leak and if its screwed too far it could break the fitting depending on the material....thats why dope may be better than tape it probably doesnt make the fitting very tight like the tape would but makes a good seal

Yellow PTFE tape (aka Teflon) is supposed to be used for sealing gas pipe thread, and white PTFE tape, for water. But is there really any difference between them? I had always thought that yellow was specially formulated to resist methane and other natural gas additives, but an HVAC tech told me the different colors are just markers, so that anyone looking at a pipe can immediately tell if it's gas or water. Other than their colors, they're just the same. Was he correct?

White = single density tape and is ONLY good for small fittings up to 3/8 in. pipe. Most people are unaware of this. "Double Density" tape used to come in white as well, but because that could be used for larger pipes, it was impossible for inspectors to know if the white tape used on 1/2" and larger pipe was in fact double density, so they stopped making it.

Yellow is now my preferred choice to use with pvc and metal water pipes. I was forced to use it over traditional pink or white tapes not being stocked. It's cost more but requires less layers and is a lot less fussy. Never had any problems.

If you use white tape on petroleum lines it will fail in a few hours or days. I know this to be true. If diesel, you will get air leaks into your lines as the lift pump pulls the fuel from the tank, causing the expected issues. If gasoline, the joint will weep fuel.

like many products they become commodities and it gets down to price, when PTFE tape was introduced to replace hemp as a thread sealant it was very successful and it became a race to the bottom trying to sell the small spools. PTFE thread seal tape became narrower the commonly used 1/2" became 12MM often shorter from 12 metres to 10 metres and became thinner so the product became very poor, because people were only looking at price per spool. Then someone with a good marketing focus decided enough of the rubbish let's offer the old style thickness and colour it yellow and market it as gas tape with a dearer price for a quality product. People appreciate the better quality and now pay more for it. Basically you get what you pay for.

Yellow = double density, required for natural gas (methane) piping 1/2" to 2" dia. pipe. In many jurisdictions you MUST use double density tape on gas piping, so inspectors will look for yellow.

Yellow is impervious to diesel, gasoline, oil, and other petroleum products, so I would assume, but do not know, that Propane and natural gas will cause white tape to also fail.

There is also green for medical gasses (oil free tape) and gray / silver for use with stainless steel and aluminum pipe (has anti-seizing compounds embedded in the tape).

Pink = triple density, required for NPT threads 1/2" to 2". Again, most people are unaware of this change and hardware stores rarely sell it for the DIY market, but if you are going to get an inspection, this is what you must use now. This is also good for gasoline and propane lines.

The companies that make stun guns specify that the weapons should be used conservatively, only for self-defense or incapacitating an unruly person. Unfortunately, stun guns are commonly used as torture devices in many parts of the world.

Standard Ptfe tspe should not be used on oxygen lines. There is a green ptfe tape made specifically for this. If you have ever disassembled a ptfe joint you would know that the tape is smashed and stretched in the joint spaces until it does not resemble tape. I have found that the white tape actually flows into the spaces better than the yellow tape creating a better seal. A plumber told me that he uses white ptfe tape and Rectorseal#5 on every joint and never has a leak. I adopted this technique 20 years ago and can report that he is correct. The plumbing code makes no reference to which color tape to use other than it must be an approved type. Yellow ptfe tape is merely thick than white. They are both made of the same material. I have also noticed that it is more difficult to wrap the wellow tape on pipe thread and get it to stay. You have to stretch it more which also makes it thinner. Use whatever you want but rest assured white ptfe is approved for gas and other flammable liquids as a thread sealant.

One popular variation on the conventional stun-gun design is the Taser gun. Taser guns work the same basic way as ordinary stun guns, except the two charge electrodes aren't permanently joined to the housing. Instead, they are positioned at the ends of long conductive wires, attached to the gun's electrical circuit. Pulling the trigger breaks open a compressed gas cartridge inside the gun. The expanding gas builds pressure behind the electrodes, launching them through the air, the attached wires trailing behind. (This is the same basic firing mechanism as in a BB gun.)

I know from handling it that it is clearly heavier. One or two wraps would be equivalent to to six or eight of the white stuff. It is rated for slightly lower temperature. *** After some minor research, evidently there are differences, however, as I see it, these differences are way beyond the scope of the common everyday amateur or even most professionals, i.e. the yellow stuff is rated for 10,000 Lbs. It is considered double density. The white is considered single density. There evidently is a red type also, that is triple density. The red tape is for large diameter pipe, 2" and above. (I've never seen that). The white is rated for something less than 10,000-Lbs. The yellow is rated for +500°F. The white is rated for +450°F. Are you getting my drift.

Tasers are only one way to conduct current over greater distances. In the next section, we'll look a relatively new long-range stun weapon that doesn't use any wires at all.
