Synthesizing Thiokol Rubber into a Bouncy Ball Attempt

Observe the step-by-step synthesis of Thiokol rubber using common chemicals and the subsequent attempt to form it into a functional bouncy ball.

Short Summary

  • Successfully synthesized Thiokol rubber by reacting sulfur with sodium hydroxide solution, forming necessary polysulfides.
  • The subsequent addition of 1,2-dichloroethane successfully precipitated the polymer, causing it to clump together into a discernible shape.
  • The resulting polymer exhibited squishiness but solidified into a rectangular cube, failing the goal of producing a round bouncy ball.

Description

For this one, I'm going to try to synthesize a bouncy ball. Basically I'm making something called Thiokol rubber, and hopefully as a ball, it'll be bouncy. #shorts

FINALLY!! The clear liquid in the start is WATER and not some alcohol mixture or something.

I'm so relieved when I see a new video from Nigel that he's survived his latest shenanigans

Maybe doing the final stirring step in a round bottom flask would result in a rounder ball.

Thanks for the tutorial!!! Finally I don't have to buy bouncy balls for my kids anymore and instead can just make them at home, which is always healthier. 😊

This is one of the rare times that he actually failed an experiment ❤❤

You know the process is diabolically slow when Nigel has to speed it up 120 times.
