What a bottle rocket

Tails of the Gun   When bottle rockets are banned only the Japanese will have bottle rockets.  And what a bottle rocket! Made by Japanese company Maruda, the RPG-7 PET Bottle Launcher is meant to be used only with 1.5L soda bottles that have been filled with water. To give you an idea of its potency, when shot at a 35º angle the toy can launch a bottle filled with 0.6L of water up to a distance of 35m (approx. 115ft). Currently it seems like the launcher is available only in Japan, but there are ways around that. Maruda is selling the RPG-7 for ¥28, 350 (~$361 USD). You can also order individual parts on Maruda’s website, including a cone warhead for the bottle. I like stuff like this.  The Second Amendment's intent was to give us recourse when government went rogue,  which according to Jefferson is inevitable and continually (ahem).  Given the technology, today's  citizenry  cannot hope to square off against the government's army on an equal basis, and must depend on fervor, commitment, guile, and ingenuity. This is the ingenuity part  I imagine this could be similarly juiced.
