Miti Agrawal 7 years, 11 months ago

When you’re swimming your lungs contain at least that much air at all times and so you float. If you drown, your lungs fill with water and you sink. But after three days or so, the bacteria in your intestines will have produced that two cola can’s worth of methane and carbon dioxide and you’ll float back to the surface.
