Answer 1

It sticks to things that are not metal. The more not like metal, the better. It sticks to itself because it is not metal. It’s like when you stick a balloon to the wall. As long as the wall is not like metal. Stretching it around things that are not like metal holds it even tighter and makes it like to stick even more.
