Nimbu khatta kyun hota hai?
Nimbu aur imli khatte hain, par saabun ki jhaag chikni aur phisalan bhari kyun lagti hai?
Socho pehle… phir dekho jawab
Kyunki nimbu aur imli mein acid hota hai jo khatta swaad deta hai, jabki saabun 'base' hai — base chikna-phisalan mehsoos karata hai. Acid aur base do alag tarah ke padarth hain.
Acid: nimbu, imli, sirka aur dahi mein thoda-thoda acid hota hai. Isliye woh khatte lagte hain. Kyun khatte? Kyunki acid ka swaad hi khatta hota hai.
Base: saabun aur mitti ke kuch ghol chikne-phisalan bhare lagte hain. Bade kehte hain ki base ka swaad kabhi nahi chakhna chahiye — saabun peene ya chakhne ke liye nahi hota.
Ek nazar: khaane ki khatti cheezein chakh sakte hain (bade ki haan ke saath), par ghar ki saafai ki cheezein sirf bade hi chhuyenge.
Ghar pe try karo
Bade ke saath rasoi mein khatti cheezon ki list banao: nimbu, imli, dahi, sirka... Chakhna zaroori nahi — bas naam likho aur sunghne se pehle bade se poochho.
Wow!
Kachcha aam khatta hota hai kyunki usme acid hota hai — pakne par swaad badal jaata hai!
Mummy-Papa ke liye
Aaj bachche ke saath rasoi mein khatti cheezon ki list banaiye aur poochiye: 'Yeh khatti kyun hai?' — jawab mein 'acid' shabd sunna kaafi hai.
