It costs $1500, measures in at about 4 feet in diameter and causes an explosion in the sky almost half a mile long. It's the infamous Yonshakudama firework from Japan and if you can somehow snag the sky lighting cannonball before July 4th and shoot it up at your local park, you'd probably become king of America.
This video shows first of all some still pictures and then video of the amazing 48" diameter 420kg Japanese "Yonshakudama" shell "the world's largest single firework"
When fired the shell rises to over 2,700ft with a bloom diameter greater than 2,400ft and launched every September 9th and 10th for the Katakai-Matsuri Festival in Katakai town, Ojiya-city, Nigata prefecture Japan, it serves as a dedication to the god of the shrine. The Godzilla waking "Yonshakudama" shell comes in two types, the "Brocade crown over small flowers" and the "Floral shell of shells twice blooming"
