Safety and Liability Disclaimer

This launcher design will always remain experimental and is not a toy.

Pressurized systems are inherently dangerous.

Adult supervision is always required.

Any kits are made available for convenience and are not warranted for suitability for a particular purpose. Design or manufacturing defects may exist. A responsible supervising adult must make a determination of whether your particular combination of printed and non-printed parts, ground anchoring systems, bottles, hoses, pressurizing systems, personal protective equipment, protocols, users, and environment are safe for your application. 

The launcher must be firmly anchored to the ground for use. Never point at anyone or anything. No one should ever have any body parts above a pressurized bottle, as the bottle may disengage unexpectedly at any time and cause injury. Heat may cause deformation of parts and all parts should be inspected before every use.
