    I need some help. I am trying to figure out what material is used in the bendable gumby toys. There is a thin metal skelleton encased in the rubber and I need to know what it is. Also, I am curious why there are holes in the rubber where one would normally bend the toy. What are the purpose of these holes? Anyone's help is greatly appreciated.
