Picture this, you just got done taking a massive dump, you whip, flush the toilet, and then wash your hands. Well, not exactly. Warning: do not watch this video if you are a clean freak. 

Don't be shy, it's okay to admit you flush the toilet without closing the lid. Many of us do it too. But once you realized how much water your toilet expells per flush you'll never again infect your bathroom with thousands of tiny droplets of poo water.
