I am enrolled this semester in a public speech class and have been assigned to prepare two persuasive speeches arguing both sides of an issue. My idea is to argue the pro's and con's of haunting with home-made PVC air rams for pneumatics. I know there are haunters out there who are on both sides of this issue. I would love input from my fellow haunters for my speeches. I believe there are valid arguments for and against using PVC in home haunt pneumatics. Thank you in advance for you assistance.
