Did any one here shocked someone with electricity from he's finger or hand?

did anyone shocked someone, with electricity here, from he's hand, finger, or head? i have been shocked many times, also i shocked people other times

mostly it's like a bug on your hand, and time times like needle, sometimes, like when you put your legs directly on floor and touch the computer screen if you don't have this in your home "terre" (in french)

how can that be explained? and why?
and why does the body get electrified sometimes?

Static electricity refers to the build up of electric charge on the surface of

objects. The static charges remain on an object until they either bleed off to

ground or are quickly neutralized by a discharge. Although charge exchange

can happen whenever any two surfaces come into contact and separate, a

static charge only remains when at least one of the surfaces has a high

resistance to electrical flow (an electrical insulator). The effects of static

electricity are familiar to most people because we can feel, hear, and even

see the spark as the excess charge is neutralized when brought close to a

large electrical conductor (for example, a path to ground), or a region with an

excess charge of the opposite polarity (positive or negative). The familiar

phenomenon of a static 'shock' is caused by the neutralization of charge.

Yes.

 

No, that never happened to me.

 

Not with me......but I heard it happen to someone.

 

.

well, it happened to me, my brother, my sister, my cousin, my other cousine, 2 of my classmates, hmm, it seems we are all electrified here, lol

 

I'm continuously shocked by the foul language you use. :spank:

 

.

lol

 

So you wear your hair long, huh?

 

And dresses?

Anomalous static-electrical shocks can be eliminated somewhat by a known cause and remedy. Use of fabric softener (dry sheet or liquid) in the laundry. Fabric softeners work by coating the surface of the cloth fibers with a thin layer of chemicals (aluminum salts or a natural type-Lecithin/soy-based, etc.); these chemicals have lubricant properties and are electrically conductive, thus making the fibers feel smoother and preventing buildup of static electricity.**

Preventing explosions

Gasoline, other inflammable fluids and fine dust can explode when ignited by a static electric spark.

Gasoline explosions

People who are filling a gasoline container at the pump are advised to use caution to avoid static sparks. When you slide out of your car, touch something metal to get rid of any excess charges. It is also recommended to place the container on the ground when filling it.

...Fires caused by static spark igniting gasoline

When many gallons of gasoline are transferred from a truck into the underground tank at a filling station, there is a lot of friction caused by the gasoline flow. Also, since the fuel is very flammable, a single spark caused by static electricity could cause an explosion.

Thus, the truck uses a grounding device on the hose that draws the electrical charges away from the gasoline, preventing any static sparks from occurring.


Dust explosions

Fine dust in a grain elevator can be ignited by a static electric spark, creating an explosion in the storage facility. Coal dust explosions have been seen in coal mines, as have explosions in wood-working facilities.

Safety precautions have been legislated for these industries to dilute or prevent the dust, as well as to eliminate static electricity sparks.
