Because when you pull off your sweater the electrons are causing a positive change that forces electrons stay on and to cause a spark to appear.
you see "lightning" (it's static you nimrod Jus kiddin lol) when you remove an wool sweater in winter because the electrons from your shirt underneith are getting more electrons added to them from the wool sweater, the electrons cause static and you may see sparks.
You can make the balloon stick to the sweater by creating static electricity on the sweater. Rub the balloon against your hair or a wool sweater to create a charge, then place the balloon near the sweater to make it stick due to the static electricity.
When you pull a wool sweater over your head, friction between the sweater and your hair can create static electricity. This static charge causes your hair to stand up as the individual hairs repel each other due to having like charges.
When a cotton shirt and wool sweater rub together, they create friction that can generate static electricity. This can cause the fabrics to stick together or even produce a small spark. The different properties of cotton and wool fibers rubbing together create a charge separation, which results in static electricity.
An insulator.
A mens wool sweater costs 5 million dollars.
because the yarn in the sweater is cleaned and died and the wool on the sheep is not
no
A wool sweater and a waistcoat are clothing items. A winter coat, windbreaker and wrap are clothing items.
The sweater was made of wool. They attempted to make a sweater from the bags.
A sweater
It really does not have anything to do with cold days but with very dry air. Your hair will stand up due to static electricity.
