 Apparently the firework that gets set off in this video has the largest firework in the world. According to the caption for the video the shell on it is 48 inchs which somewhere around three to four feet in diameter. That is a big shell boys and girls. When you see this firework explode it seems to just disperse a lot of smaller fireworks like a grenade. The smaller fireworks fly outward and then explode themselves creating a giant flower mum shape. And of coarse the video is taken somewhere in Asia.
Check out the giant firework explosion for yourself. Source: Big-boys.com |
