Is it possible to eat and sing at the same time?

So usually i sing covers on sarmaker to improve my singing ,i even have a youtube channel on some of my covers and practices. But this one time i decided to record and most something different that no one tried before( or atleast i think so) singing and eating in the same video recording to see whether it will affect my voice by either one of these acts. So listing the video ,go check it out and tell me what my final results were !! Because i personally think it is highly possible. Lol
