New Self Healing Rubber

I read in the news that a professor in Paris came up with a self-healing rubber. They think its applications could range from adhesives to tires for bicyles. One can break a piece in parts and put them back together over and over... I don't know why, but it reminds me a popular toy back when I was a kid. I believe its name was "slime", it was green. You could not have made a tire with it, but you were able to put it back together over and over... :)
