As we often see in questions a lot depends:

Do you need a flexible material
How fast do you need it to break in water
Does it need to be rain proof but not water proof.
Does the cross sectional area matter.


I would go the paper route personally - Twisted paper if necessary to get the strength BIT this won't instantly fall apart in water.

There are numerous solids that will be quite strong in air but are water soluble.

many papers
anything with water soluble glue (spaghetti as burf mentions)
lots of ropes lose strength when wet (fibers soak it up and get fatter/less twisted/less strong)
