What polymers are bouncy balls made of?
There are two polymers working together to make your bouncy ball bounce that high. Polyvinyl acetate, a strong and flexible polymer, is found in glue. Amylopectin, a “branched” polymer, is found in cornstarch. The polyvinyl acetate gives your ball strength while amylopectin gives your ball elasticity.

Batteries are dangerous in the stomach acid. Since the ball is small enough it should pass with no problem.
Why is rubber not elastic?
The ratio of stress applied on a body to the strain produced in it is defined as the Young’s modulus of that material. Rubber gets stretched because there is strain produced in it when stress is applied. The larger strain means the material is less elastic.
Is wood more elastic than steel?
Answer: Explanation: So, it can be said that for a given amount of stress, the strain produced in the steel is comparatively smaller than the strain produced in the rubber.
