new rubber mends itself when broken

This article is about french scientists creating a rubber that can mend itself when broken.
The rubber is called material B, and it can stretch alot more than its original length,and when breaks it can mend its self together.After 15 minutes it should be okay to stretch again.a sample can be stretched about 200 per cent without breaking.
The scientists sayd you can fel the mending of the ruber when u hold each side of the fractured rubber,and they say its a very strange feeling.
They say that it could be used for childrens toys.When the rubber is back together,the rubber is not visable there it was teared,and it will break again at the same place unless it heals for a long time.The cycle of breaking it and reparing it can be done alot of times said the researchers.


my opinion
i think that the rubber that can mend itself is really cool,i never thought they would come up with something like that in the world.i dont really like the urine part of making it i didnt expext to read it like that and that they would use anything like that.
but its really cool the rubber it self.
i like it.
