Hum sabhi bachpan se hi jaante hain ki pani geela hota hai, lekin kya aapne kabhi socha hai ki aisa kyun hota hai? Vaigyaanik drishtikon se isko samajhne par pata chalta hai ki ye sab kuchh dravon ke gunon aur satahon ke sampark par nirbhar karta hai. Darasal, pani ki geelaapan ki prakriya uski satah par chipakne ki kshamta se judi hui hai. Jab pani kisi vastu ki satah par failta hai, toh woh us satah ke saath raasaayanik aur bhaautik sambandh banaata hai, jisse humein geelaapan mehsoos hota hai.
Vaigyaanikon ke anusaar, kisi drav ka geelaapan is baat par nirbhar karta hai ki woh drav kisi satah ke saath kitni achchhi tarah sampark bana sakta hai. Isko 'sampark kon' (Contact Angle) kaha jaata hai. Agar sampark kon chhota hota hai, toh drav us satah par achchhi tarah failta hai, jisse geelaapan adhik mehsoos hota hai. Udaaharan ke liye, pani sheeshe ki satah par fail jaata hai, jisse woh geela dikhaai deta hai. Waheen, agar sampark kon bada hota hai, toh drav golakaar boondon ke roop mein rehta hai, jaise ki mom ki satah par pani.
