You are aware that we are talking about water, right? "If used improperly it can kill you, even in small amounts." - Pour some in your lungs, see if it doesn't. I'll wait. "...mortuary cleansing agent, but I'm guessing its more than just H2O." - You'd be guessing wrong. Water is what is primarily used. **Evaporation**, the process by which an element or compound transitions from its liquid state to its gaseous state below the temperature at which it boils; in particular, the process by which liquid water enters the atmosphere as water vapor. **Biodegrade**, to break down, essentially into innocuous constituent products by the action of living things (such as microorganisms) **Not** the same. "Plastic water bottles stored on grocery store shelves for more than a month have been tested and found to contain high levels of dihydrogen monoxide, enough to kill a full grown adult." - refer back to the first entry. Try pouring a 500ml bottle of water into your lungs. See what happens. Again, I'll wait. At first I thought that you might just be trying to troll me. But then I realized that you genuinely don't know just how much you don't know, do you? Don't worry. It's not all your fault. I blame the elementary school system. You are obviously not yet tall enough for this ride.
