*I have long suspected that my children steal my drinking cups throughout the day. I imagined them backwashing into the cup. Never have I had visual proof, only sticky fingerprints and questionable floating pieces of food left in my drink. Zack was able to finally capture on video what goes on when my cup is left unattended. To further illustrate how horrible it is, he added slow-mo to the video.
*Never again will I leave my cup in easy to reach places...oh my word.
