Video narration
Aakhir ek aatishbaazi jaisi cheez hathiyaar kaise bani? Kahani China se shuru hoti hai. Wahin gunpowder, yani baarood, ke saath prayog hue. Logon ne dekha ki nali mein baarood jalne par dabaav banta hai aur cheezen baahar dhakeli ja sakti hain. Isi vichaar se fire lance bana - ek nali, jo bhaale jaise hathiyaar se judi thi. Yah lau, dhuaan, chingaariyaan aur tukde phenk sakti thi. Lekin fire lance bandook nahi tha. Woh aag dikhaata tha, thos goli nahi chalaata tha. Phir mod aaya: nali ne aag ugalne ke bajaay thos prakshepy chalaana shuru kiya. Majboot dhaatu ki aisi nali se bana hand cannon, yani haath se sambhaala jaane wala chhota top jaisa hathiyaar, bandook ka pehla spasht roop tha. To pehla gun kisne banaaya? Kisi ek vyakti ne nahi. Yah vikaas dheere-dheere hua. Jawaab: China mein fire lance se vikasit hokar hand cannon bana - yahi pehli bandook ki shuruaat thi.
