YouTuber Uses a Hydraulic Press to Test How Durable Hardened Glass Is

It's mesmerizing to watch the glass flex before it eventually shatters.

If you haven't seen the Hydraulic Press Channel, you are missing out. The YouTubers behind it test everything using hydraulic presses from metals to car springs.

In this edition of their show, they test hardened glass. They test two films of glass with different thicknesses: 0.078 in and 0.23 in (2 mm and 6 mm). 

They place the glass on two wooden planks and use another to push the glass in the middle. "We are going to see how much it's going to flex and how much force it's going to take before it explodes," says the YouTuber.

The YouTuber also issues a warning to anyone watching not to try this at home as the breaking glass will send many pieces flying and even create enough dust that the YouTubers are required to wear breathing masks.

The first glass is the thinner one. It is impressive to watch as the glass flexes a lot before it breaks. What pressure was required for it to finally shatter? The meter reads 80kg. Not bad for such a thin piece of glass.

Can you now guess what it will take for the thicker piece to shatter? We won't tell you here. Instead, we will let you watch the video and be surprised.
