Woman investigates after noticing strangely placed mirror in restaurant bathroom

On Nov. 4, TikTok user Stacy Ceja uploaded a video inside the bathroom of her local açaí bowl spot. she had spotted a mirror on the wall right across from the toilet. Upon investigation, Ceja realized that it might be a two-way mirror. According to wikiHow, one way to tell whether or not a mirror is two-way is with the fingernail test (which Ceja used). if the mirror is two-way, you won’t be able to see the reflection of the tip of your finger.

TikTok user Samantha Trottier later investigated the restaurant’s bathroom mirror for herself and discovered that it was, in fact, just a regular mirror.
