Secret ingredient is urine....

Self-healing rubber bounces back

A material that is able to self-repair even when it is sliced in two has been invented by French researchers.
The as-yet-unnamed material - a form of artificial rubber - is made from vegetable oil and a component of urine.

The substance, described in the journal Nature, produces surfaces when cut that retain a strong chemical attraction to each other.

Pieces of the material join together again as if never parted without the need for glue or a special treatment.

Compunds with hydrogen bonds are often hydrophillic. Wouldn't this stuff dissolve in water?

And I am betting the urine compound is urea?
