Nerf Dart Launcher
For my engineering class i decided to create a nerf dart launcher. I used pvc pipes to create it and used a valve to activate it.
To start attach a few pvc pipes and then put an attachment on the bottom of the pipe and that will later be inserted into the air compressor.
Next you add a valve onto the middle of the pipeline and that will be used to send air into the pipes and propel the dart.
And after you complete steps 1 and 2 you attach a larger pipe onto the end for to put the dart into and then you have completed your nerf dart launcher.
