Not only that but it is quite easy to build and very cheap. You can fire many different types of projectiles and many can make it up to 300m into the air! It took only a weekend to build, the only slow part was having to wait for the glue to dry. This is all i needed...

This method uses food as fuel. It is much safer than alcohol or other fuels, not only because it is non-toxic, but also because the fuel is not really flammable until you blow it. It won't burn if yo...
