This glass is indestructible (nearly)

Показать описание

I recently discovered a type of glass called Superfest, and I think it's pretty cool. Years ago when it was made, it was called a nearly indestructible glass, and now I want to test that.

The glass is made with the same technology behind Gorilla Glass. The general idea is to exchange the smaller sodium ions that are on the surface of the glass, with larger potassium ions. This increases the pressure between the core of the glass and the surface, meaning the glass has to bend more before it will break. This also makes it less likely to scratch, which is the benefit to phone screens.

A minute of silence for the glass, the dish, the round bottle, the beaker, and the (nearly) indestructible glass.

The best thing about it was that they wanted to make glass that was 5x stronger than regular glass, but it turns out it was around 15x stronger. Peak of East German engineering.

The "Superfest" glass was created in GDR Germany but no one wanted to sell it in their shops because the shopkeepers were worried that such durable glasses worsen their sales over time. Therefore the business model ironically... shattered.

One reason it shattered may have been because you threw it onto a bunch of other glass shards. The Superfest glass can still be easily shattered if force is applied quickly to a small portion of surface area, so pebbles, glass shards or even sand grains on the floor can pop it like a balloon if it lands directly on top of them at the wrong angle. It's still much more durable than normal glass.

forget the durability of the glass, the floor is the only truly indestructible thing in this lab

The way his face impression gets just more and more excited as he continues to destroy things is just so funny, get this man into one of those rage rooms where you can smash things and he will be like a kid in the candyshop😂

This video was just an excuse to break glass without looking like a lunatic

Saw a video recently on these. They failed basically because people never needed to replace them. Decades later, many bars and restaurants in Germany still have their original stock of Superfest glasses.
