Yeah! that's a true story,but you know alexbeyman?
The first rockets were probably the result of a side invention of the manually fired fire arrow, which was essentially an arrow strapped with gunpowder fired from a bow. According to Liang Jieming, two Song dynasty generals by the name of Yue Yifang and Feng Jisheng invented a variant fire arrow which used gunpowder tubes as propellant. However more documentary evidence of rockets does not appear until the 13th century.Rockets may have been used as early as 1232. There were reports of fire arrows and 'iron pots' that could be heard for 5 leagues (25 km, or 15 miles) when they exploded upon impact, causing devastation for a radius of 600 meters (2,000 feet), apparently due to shrapnel.[1] Rockets are recorded to have been used by the Song navy in a military exercise dated to 1245. Internal-combustion rocket propulsion is mentioned in a reference to 1264, recording that the 'ground-rat,' a type of firework, had frightened the Empress-Mother Gongsheng at a feast held in her honor by her son the Emperor Lizong.
