I am referring to the doors (or rather, door knobs) I am encountering here. Thanks to the cold and dry weather, I get 'shocks' when I touch the door knobs often. Static charges build up over a period of time in our body through the dry air and on the skin. Through the metal on the door knob, it gets discharged. It is a not-so-funny and a unique phenomenon. Never heard of it in India.. The effect is more when
a) when one is wearing shiny jacket, such as the ones made of rexin
b) when one gets lotsa friction with a fabric
c) the room has some high-voltage electrical or electromagnetic equipment
d) when the temp (less than 5 C) and the humidity (less than 30%) are low
It reached a peak when I saw a tiny spark while touching my car window.. Serious.. I must have been fully charged up... Cellphone explosions due to the static discharge has been somewhat prevalent.
Some tips on minimizig/avoiding the shocks:
i) Try to grab the knobs or any metal thing with the palm, rather than delicately touching through the fingers.. More the surface area for discharge, less will be the current density.
ii) Usually the doors have a glass window knitted with metal wires. Running your fingertips on the glass for about half-a-feet would smoothly discharge it through the glass.
iii) If you already have a leather jacket, use it; I am not recommending buying a new one (my previous post would say why).
iv) After wearing/removing any other jacket, walk up to the door, discharge in the glass window and come back to ur place. You can get shock from any metal object you touch.
v) Try not to use a cellphone near a gas station.
Have a good (shock-free) weekend, friends!!! :-)
