the charge flows from high density to low density if there is some high density of charge concentrated in one place it tries to move to a low density place in the process the electrons move int the for which appear like spark

This is a result of Discharge!..... The charge is distributed from the highly charged object to earth (or a lesser charged, or even oppositely charged object).
As the charge transfers, any gases in the path turn to plasma, and this is the bright spark you see.
If sparking is continuous, there may also be a smell of Ozone.... Just be careful not to get your nose TOO close to the Sparks!!!

This can be thought of as an attempt by the universe to neutralize the charge.
When an object with an excess of electrons (negativly charged) is introduced to an object with a deficit of electrons (positively charged) the excess electrons want to fill the holes left by the lack of the electrons on the positively charged object. This causes the electrons to "flow". If this flow happens through air, you see a spark, which is actually energy given off by the moving electrons.

Air is an insulator. So of course electricity cannot flow though it.
However, as you charge an object more and more its potential rises (that is, the potential energy of the free electrons in it rises - that is what a voltage is - a potential energy per charge).
When it is high enough, it can cause the air to ionise - that is, molecules in the air lose an outermost electron and become charged. Ionised air is quite a good conductor, so a current begins to flow. This is seen as a spark, because the flow of current heats up the air.

Everything wants to go down hill.
This is only one law of physics and it is written many different ways.
In the case of electricity the steepness of the hill is not a diffecerence in height, but a difference in the number of electrons. Imagine air is a car with a really good park brake. Imagine metal is a billycart with no brakes. An difference in electrons (height) between to points on a piece of steel and the cart will roll straight away.
A difference between to points separated by air....well you have to make that hill pretty damn steep to overcome the park brake. But when it goes, it goes with a bang.
So this is why you get a jump. It builds up and up and up. When the air can not hold it back any more. BANG.

does it junp or does it travel in the charged earth around the sparks point of ignition....

Because it has an energy specifically kinetic energy.

Did it jump or was it pushed?
