Abstract

Three different types of pipes were tested to see at what point in time they would break. The pipes, PVC pipe, PEX pipe, and CPVC pipe, were filled with water and attached to a helium filled weather balloon. The ends of the pipes were sealed to trap the water inside. The pipes were secured onto a payload in a Styrofoam box surrounded by cheese cloth. This frame secured the pipes and ensured that they stayed in one place and could not move around the container. The balloon and payload were then released and climbed approximately 92,000 feet above the original point of launch. The purpose of the experiment was to test the reliability of the pipes by way of stress through expansion pressure caused by the frozen water. It was predicted that the pipes would burst due to the pressure provided by higher altitude and colder temperatures of around -50 degrees Celsius. The pipes are not made to withstand temperatures and altitudes such as these. Only the CPVC pipe broke under the stress that near space provided.
