Full Idea
A future accelerator might create 'stringballs', when two strings slam into one another and, rather than combining to form a stretched string, make a tangled ball. Finding them would prove string theory.
Gist of Idea
String theory might be tested by colliding strings to make bigger 'stringballs'

A Reaction
This is the only possible test for string theory which I have seen suggested. How do you 'slam strings together'?
