Caution Failed Attempt

I have worked on the gene gun this week and had no success. But I only fall to get back up again and try. I was missing some threaded tape to seal the threads between the metal for a more pressurized seal. I was trying to reach a goal of 80psi but only got to 60psi before the rubber line ruptured and leaked the air. I have modified the gene gun with some duck tape because of my lack of finances in my project. I have also posted a pic of a joke below the modified gene gun. Can anybody tell me if they get the joke.
