This is how Google annihilates hard drives it doesn't need anymore

It's hard to get a look inside Google's famous data centers — you'll need a security clearance, and there are iris scanners to make sure you can't get in if you don't have it. But Google has been pushing its cloud platform to new customers recently, so it released a fascinating eight-minute video that gives us a peek inside a data center.

There's a lot of interesting tidbits in the video, but my favorite part is around the five-minute mark, where you can see Google's massive hard-drive shredder — basically, a wood chipper for data storage — tearing through a hard drive that had outlived its useful life.
