This trick can save your life. Build your own floating device using your pants. Once you get your pants off, you're gonna tie the two ends of your pants together like this, zip up or button up your pants, and this is the hardest part, you're gonna grab it by the sides, you're gonna slam it down and get as much air in there as possible. Now all you gotta do is put your head through it. And this is how you stay afloat.
