A popular YouTube personality uploaded a video this week demonstrating a technique used by the U.S. military to fold a t-shirt.

The video, which has amassed nearly a quarter-of-a-million views on YouTube, shows the “Crazy Russian Hacker” explain a method aimed at allowing travelers to maximize their packing space.

Here are the steps:

1.) Place the shirt on a hard surface and fold the bottom few inches inside out to create a flap.
