Super Elastic Bubble Plastic was a tube of liquid plastic that came with a blow straw. It’s a type of toy that is made from a stretchy, translucent plastic material. The elastic plastic is typically formed into a small, round shape that can be blown into a bubble, stretched, twisted, or bent into various shapes and forms and was popular in the 1970s.
The toy utilized the elastic properties of the plastic material, which allowed the plastic to be formulated to be stretchy and flexible, allowing it to be pulled and twisted into different shapes.
