Chham-Chham Paani, Ghoome Chakki
Nadi ka paani pahad se neeche aata hai. Kya woh kuch kaam kar sakta hai?
Socho pehle… phir dekho jawab
Haan! Girta paani zor se dhakka deta hai. Woh badi chakki ghumata hai, aur chakki se bijli banti hai.
Upar rakhe paani mein taakat chhupi hoti hai. Jab woh girta hai, toh taakat dhakka ban jaati hai. Jitna upar se gire, utna zor!
Pahad par log nadi rok kar paani jama karte hain. Phir paani neeche girta hai aur ek badi chakki (turbine) ghoomti hai. Chakki ghoomi — bijli bani — ghar mein bulb jala!
Chant: 'Paani gira, chakki ghoomi; chakki ghoomi, batti jhoomi!'
Ghar pe try karo
Kaagaz ki phirki lo. Bade ke saath sink mein mug se paani daalo — pehle phirki ke paas se, phir thoda upar se. Kab phirki tez ghoomi? (Paani ke khel ke baad farsh pochh lo, taaki koi phisle nahi.)
Wow!
Tumhare ghar ka bulb shayad kisi pahad ke girte paani se jal raha ho!
Mummy-Papa ke liye
Aaj sink mein mug se paani gira ke bachche ke saath phirki chalaiye, aur poochiye: 'Upar se giraaya toh tez kyun ghoomi?'
