and please with no maths? it's late and i'm tired. But it's bugging me.

Popular philosophy using analogies that are meaningless at those scales that's completely untestable and has to constantly invent new dimensions in an attempt to solve the ridiculous solutions it comes up with. It is unprovable, predicts nothing and has little to do with science.

The basic idea behind all string theories is that the fundamental constituents of reality are strings of extremely small scale (possibly Planck length, about 10-35 m) which vibrate at specific resonant frequencies.[2] Thus, any particle should be thought of as a tiny vibrating object, rather than as a point. This object can vibrate in different modes (just like a guitar string can produce different notes), with every mode appearing as a different particle (electron, photon etc.). Strings can split and combine, which would appear as particles emitting and absorbing other particles, presumably giving rise to the known interactions between particles.
In addition to strings, string theories also include objects of higher dimensions, such as D-branes and NS-branes. Furthermore, all string theories predict the existence of degrees of freedom which are usually described as extra dimensions. String theory is thought to include some 10, 11 or 26 dimensions, depending on the specific theory and on the point of view.

Not fully in less than a hundred words, but basically it is the theory that all matter is made up from strings of pure energy.
It is a very difficult subject in the early stages of research, but very interesting. There are a number of books on the subject, and suggest you get a good nights sleep, then go to your local library and read up on the subject. Also in this field is the study of quantum physics and mechanics. Hope this helps.

Certainly:
String theory is a model of fundamental physics whose building blocks are one-dimensional extended objects (strings) rather than the zero-dimensional points (particles) that are the basis of the Standard Model of particle physics. For this reason, string theories are able to avoid problems associated with the presence of point-like particles in theories of physics, in particular the problem of defining a sensible quantum theory of gravity. Studies of string theories have revealed that they predict not just strings, but also higher-dimensional objects. String theory strongly suggests the existence of ten or eleven spacetime dimensions,[1] as opposed to the ordinary four (x, y and z axes and time).

In physics there are two sets of universal laws. Set 1 relating to large objects: solar systems, planets, the movement of the stars etc. Set 2 relating to small objects (nuclear physics) subatomic particles. These laws do not apply to each other. Set one cannot be applied to small objects and set 2 cannot be applied to large objects.
String theory is an attempt at a truly Universal scientific law. Strings are supposed to be the particles that everything in the universe is made from. And so any laws of string theory would apply to everything in the universe.

Are you just getting people on a bit of string?
But maybe now I come to think about it the strings on musical instruments take a lot of theory, or "Are you stringing me along"
How long is a piece of string?
when does twine become string or vice versa,
Or to string somebody up for instance "Ian Brady" maybe the horizontal plum-bob would make an interesting theory.
Now I'm bloody tired.

How about "String theory is branch of theoretical physics" Seven words!

no, but i know that a college essay question went something like this:
"String has affected history in many ways. The string on Thomas Jefferson's kite when he was inventing the lightbulb, (they put another example but i forget what it was) ___, please explain to us one way that string has changed your life."
hehe. good luck. you can to go math.com and maybe it will be able to tell you.

Yeah, you got everyone stringing along wi this one.
