string

String is a long flexible tool made from fibers twisted together into a single strand, or from multiple such strands which are in turn twisted together. String is used to tie, bind, or hang other objects. It is also used as a material to make things, such as textiles, and in arts and crafts. String is a simple tool, and its use by humans is known to have been developed tens of thousands of years ago. String may also be a component in other tools, and in devices as diverse as weapons, musical instruments, and toys. The ubiquity of string as a tool has led to conceptual and scientific uses of the term, including strings in computer science, cosmic strings, and string theory. thumb|Two pieces of string under a light microscope

== History == String, along with twine and other cordage, was used in prehistoric times for hafting sharp stone tips onto spears, in beadwork, to ease firelighting (as part of a bow drill), as well as for fishing lines and nets, clothing, shelter-making materials, bow string, sutures, traps, and countless other uses.
