Note: This is an outdated (and in fact erroneous) version of the article about Liu Xing Pao, kept here for archival purpose. The article has since been retracted, and information about Liu Xing Pao is added into my blog post about rocket weaponry.
Liu Xing Pao (流星砲, lit. 'Shooting star bomb', not to be confused with other weapons with similar names) is a poisoned barbed javelin with a large firecracker attached to its bamboo shaft. The firecracker is not intended to cause harm, but to disorient enemy troops and startle enemy horses with its bright flash and loud bang.
