DIY soda bottle launcher makes recycling more exciting

Looking for a new way to get your family interested in recycling? Don't just collect your empty soda bottles; shoot them into the recycling bin with a homemade soda bottle launcher. YouTuber NightHawkInLight has created a simple yet effective soda bottle launcher that utilizes a propane torch for fuel. Embellished with coiled tubing that lights up during each launch, this example of DIY know-how is the perfect weekend project.

According to Eric Limer for Popular Mechanics: "The launcher operates on basic potato-gun principles. A bottle at the end of a PVC barrel is filled with an air-propane mixture which when ignited sends the bottle flying off into the distance with a cloud of flame and a hell of a boom. What makes this particular application so great though is the flourish—the circular path the pilot flame takes, building up some tension before the big event."
