Kabhi aapne dekha hai ki paani hamesha neeche girta hai, phir bhi kabhi-kabhi patli si jagah mein “upar” chadh jaata hai? Yeh bilkul jaadu jaisa lagta hai, lekin iske peeche science ka ek simple rule hota hai.
Is post mein hum parents aur kids dono ke liye asaan bhasha mein samjhenge ki paani patli naali ya patle pipe mein upar kaise chadh jaata hai. Is concept ko capillary action kehte hain.
Introduction
Ghar mein tissue paper, cotton, ya paudhon ki jadhon ko paani peete hue dekhna common hai. In cheezon mein paani kabhi-kabhi upar ki taraf move karta nazar aata hai.
Parents ke liye yeh ek perfect “mini science lesson” hai jo bina extra gadgets ke bachchon ko samjhaya ja sakta hai.
Main Explanation or Story
Normal condition mein gravity ki wajah se paani neeche aata hai. Lekin jab paani kisi bahut patli jagah (jaise patli naali, straw ka bahut patla part, ya tissue ke fibers) mein hota hai, to kuch aur forces ka effect strong ho jaata hai.
Capillary action tab hota hai jab paani aur surface ke beech attraction (adhesion) aur paani ke apne molecules ka saath (cohesion) milkar paani ko upar kheench lete hain. Jagah jitni patli hoti hai, yeh effect utna zyada dikhai deta hai.
Isliye patli tube, patli darar (crack), ya cotton/tissue ke chhote-chhote pores mein paani upar chadh sakta hai. Yeh bilkul waise hi hai jaise paudha mitti se paani ko upar patton tak pahunchata hai.
Key Lessons or Takeaways
- Paani hamesha sirf gravity se behave nahi karta; surface forces bhi kaam karti hain.
- Patli jagah mein paani upar ja sakta hai, isse capillary action kehte hain.
- Plants isi process se paani ko roots se leaves tak le jaate hain.
- Tissue, cotton, aur sponge paani “soak” karte hain kyunki unmein bahut saare tiny gaps hote hain.
Simple Activity or Example
Is experiment se kids ko capillary action apni aankhon se dikh jayega. Aap ise 5–10 minutes mein ghar par kar sakte hain.
- Ek transparent glass mein thoda sa paani bhar lein.
- Paani mein food color (optional) ki 2–3 boondein daal dein.
- Ek tissue paper strip ya kitchen towel ka patla strip kaat lein.
- Strip ka ek end paani mein dip karein aur doosra end glass ke bahar latakne dein ya ek khaali glass tak pahunchane dein.
- Kuch minutes wait karein aur dekhein ki paani tissue ke through upar chadh raha hai.
Agar aap do glasses use karein (ek mein colored water, ek empty), to tissue bridge banakar paani ko doosre glass mein “transfer” hote bhi dekh sakte hain.
Important Points to Remember
- Patli spaces mein capillary action zyada strong hota hai.
- Surface (paper/cotton) aur paani ke beech attraction bahut matter karta hai.
- Food color use karne se movement clearly dikhai deta hai.
- Har material same tarah se behave nahi karta; plastic par effect kam dikh sakta hai.
Safety or Guidance for Parents if relevant
Chhote bachchon ke saath food color ya kisi bhi liquid ko handle karte waqt supervision zaroor rakhein. Glass utensils ke bajay plastic cups use karna safer hota hai.
Experiment ke baad hands wash karna aur surface wipe karna achchi habit banata hai. Agar baccha cheezein muh mein daalne ki aadat rakhta ho to edible color hi use karein.
FAQs for Parents
Capillary action hota kya hai?
Jab paani patli jagah mein surface ke saath chipak kar (adhesion) aur apne molecules ke saath jude rehkar (cohesion) upar move karta hai, use capillary action kehte hain. Yeh effect narrow spaces mein clearly dikhai deta hai.
Paani gravity ke khilaaf upar kaise ja sakta hai?
Bahut patli spaces mein adhesion aur cohesion forces gravity ko temporarily “beat” kar sakti hain. Isliye paani thoda distance tak upar chadh jaata hai.
Plants mein yeh concept kaise kaam karta hai?
Plants ki stems ke andar very thin tubes (xylem) hoti hain. Unmein capillary action aur transpiration milkar paani ko roots se leaves tak le jaate hain.
Kya har liquid capillary action dikhata hai?
Nahi, liquid aur surface ke combination par depend karta hai. Water cotton/paper par strong capillary action dikhata hai, lekin kuch oils ya smooth surfaces par effect different ho sakta hai.
Is experiment mein tissue ki jagah cotton string use kar sakte hain?
Haan, cotton string bhi accha kaam karta hai. Kai baar string mein paani ki movement aur bhi clearly dikhai deti hai.

Conclusion
Paani ka upar chadhna koi magic nahi, balki capillary action ki simple science hai. Jab kids ko yeh concept ghar ke chhote experiments se dikhaya jaata hai, to learning fun aur memorable ban jaati hai.
Aaj hi tissue aur paani se yeh activity try karke dekhein, aur bachchon se poochhein: “Agar pipe aur patla ho, to paani aur kitna upar ja sakta hai?”
