I’m guessing a lot of people figured this out long ago, but I’m going to call it out just in case you never realized.
It’s really annoying when the paper toilet seat cover falls into the toilet before you have a chance to turn around and sit on it. I figured out today that you can minimize the chance that the cover will fall in by placing it such that the crease from the fold points up instead of down:
The reason the cover falls in is because the water seeps into the center flap, pulling it downward. Pointing the fold crease up causes more resistance against that downward pull. Win!
