YouTuber explains and demonstrates how a self-healing polymer works
Spoiler alert: The material is not sticky.
There's no doubt that we love YouTuber Steve Mould. In his many varied videos, he shares with us the most entertaining and educational science experiments and explanations and portrays them in a way that is accessible and easy to understand.
Now, he is back with a new clip where he explains how self-healing material works. He begins by cutting the material in two and sticking it back together.
It's clear that the material has become one again, merging both sides. He then compares this to Blu Tack as that material can also be cut and made whole again.
However, there is one difference with Blu tack and that is that the material is sticky overall. Self-healing material is not which makes its so-called merging abilities all that more extraordinary.
Mould explains how a lot of the information that pertains to how self-healing material works is hidden behind trade secrets but he does dig up some data that is quite useful in understanding the material's processes.
What is that information? What are the secrets of self-healing materials? Can they be easily replicated? What purpose do they serve? This video answers all these questions and more.
