More Bubbles, Please

This morning while I was getting ready for work, I washed out my water bottle. I know that I should throw it out and just buy a new one, but these days, that $2 is a nice chunk of change and I'm not about to toss it away when I have a perfectly good bottle to use already. So, I washed my the bottle with hot soapy water for a good five minutes. Long enough to scald myself and watch my hand turn a displeasing bright pink. I shot some dish soap directly into the bottom of the bottle, as well as around the mouth piece, filled it part way with hot steaming (did I mention scalding) water and shook the hell out of it. Instantaneously the bottle filled with tiny bubbles, then lathering suds. With my index finger and thumb I washed around the mouth piece thoroughly and finally stopped when I heard that pleasant squeak of clean plastic. I filled the bottle with fresh water and went to work.
I have since, just now, finished the bottle and have the taste of soap residing in my mouth. I took a whiff of the mouth piece and low and behold! it smells of lemon soap. So, now I am wondering just how much soap I have allowed myself to ingest and why did I not notice it before I drank the entire liter. There's a slight film on my lips and no matter how much I lick to remove it, it doesn't seem to be disappearing. Damn soap. I better not get the hic-ups.
