Water fuse launcher

cults3d

A launch system for water rockets (Coca-cola type). Fins are printed flat and attached to the bottle (glue or tape). The sealing between the nozzle and the base is ensured by two sets of rubber bands (to be placed on the grooves), I used small rubber band to fill the hollow of the grooves. The base is designed to receive a small valve (bicycle type, diameter 6 mm) which is aimed in the body below. At the exit of this hole is planned the implantation of a plastic straw (diameter 7.6 mm). This straw guides the departure of the rocket and avoids the backflow of water in the valve. The base is to be screwed on a support, to let the valve out underneath. Once the bottle is filled between a quarter and a third, turn it over on the base. A simple press prevents the water from flowing. So you can fold the hooks and hold it with the corners. These wedges have a hole for a string, so you can be at a distance for the launch. Pressurize the bottle, pull the corners to release the rocket.. I recommend vigilance and the wearing of protective glasses because in this configuration the bottle is propelled to 15 meter height.
