With this in mind, here's an analogy to help you understand static variables:
Classes are templates for things. You can imagine that as a physical analogy, they could be the mould you use to create lego blocks.
Instances are the individual blocks created by the mould. they are all of the same type as defined by the mould.
Instance Variables (also known as Member Variables) are variables that are attached to the individual instances. For example, a block might have sticky = true; because a dog slobbered all over it.
Static Variables (also known as Class Variables) are variables that are attached to the mould itself. Imagine that the mould has a detachable piece with a serial number, that number would be a static variable. Static variables are attributes of the class itself (the mould) and not the instances that are in use (the blocks).
Hope that helps a little bit to understand statics :)
