You don’t really give much thought to being stuck out in the middle of the ocean with no life jacket and not knowing if anyone is going to come and save you.
Most of us would not have the knowledge to know what to do in a situation like this, unless you were in the military.
In the featured video, a member of the United States Marine Corps teaches how to keep yourself afloat using a pair of pants.
In just a few moves, he quickly turns his pants into a life jacket that he inflates and wraps around his neck.
Watch the video carefully; someday it may save your life!
