The wafer-thin iPhone Air is surprisingly strong.

You’d be forgiven for assuming the iPhone Air would snap like a twig under pressure. It’s almost impossibly thin at just 5.6mm. But, its titanium frame is not only stronger than aluminum, it’s also more elastic. YouTuber JerryRigEverything demonstrates this with his usual bend test. While he’s able to get some slight bowing by pressing his thumbs into the center of the screen with all his might, it doesn’t crack and immediately returns to its original shape.

Not content to be thwarted by Apple’s engineering team (and perhaps feeling a little disappointed that the last several devices on his channel survived the bend test), JerryRigEverything takes a trip out to his garage. With the help of a crane scale and some metal bars he’s able to find out exactly just how much pressure it takes to crack the iPhone air — 216 pounds.
