Vat19 puts the life-saving LifeStraw water filter to the test by trying it out in sewage, urinal water, water from the Mississippi River, and even some liquid vomit. The video, naturally, comes with a warning for the weak of stomach.
This is our grossest video ever. If you have a weak stomach, you’ve been warned!?
The filter, which was created for use in developing nations where access to clean water can be limited, is also available through retailers like Amazon.
