@chemteacherphil: Rubber tires are essentially composed of a single molecule of cross linked polyisoprene. The old tire patches I use in this video are little more than metal discs filled with a combustable mixture with a thin rubber patch on the underside. When the mixture is ignited, it gets hot enough to cause the rubber in the patch to vulcanize with the rubber in the tube, creating a strong airtight patch, in spite of the fact that these patches are more than 75 years old! #c#chemistrychemteacherphil #learnontiktok
Why would they stop making those things, they seem awesome

As a 70s kid, I remember the patches you had to cut to the shape of the hole of your bike inner tube and a tube of glue. We also used tire inner tube as a float at the beaches good old days. 🥰

Someone said the reason they don’t make things how they used to is because everything is cheaper and flimsy. So the rubber on a tire we have now is cheap and flimsy that this tool would melt it.

This is how we fixed our bike tires when I was a kid. They were much smaller though.
