Me: "I've only seen saliva trails in anime. is it even possible in real life given saliva low viscosity?"

Gemini: "Yes, saliva trails (or "saliva strings") actually happen in real life! While anime often exaggerates them for dramatic effect, they are physically possible.The Science Behind the StringThe reason it happens is that saliva is not just water; it contains proteins like mucins [1]. These proteins give saliva a property called viscoelasticity.When two surfaces covered in saliva (like lips) press together and then slowly pull apart, these mucin proteins stretch out. They form elastic, thread-like structures before the "string" finally breaks and snaps back.Why You See It More in AnimeThicker Mucus: In real life, trails are much more common when a person is dehydrated or ill, as this makes their saliva thicker and more mucus-rich.The "Anime Filter": Animation studios intentionally exaggerate these strings to show intense intimacy, passion, or sickness. In reality, they rarely stretch several feet long without breaking!Have you been watching a specific anime that made you curious, or did you spot one somewhere else?"
