Step 1: The launcher
- One 1/2" four-way fitting (all fittings are of the slip variety)
- Two 1/2" end caps
- One 1" coupling
- One 1" by 1/2" bushing
- One 1/2" 45-degree elbow
Step 2: Jet tube PVC form
To make a jet form, cut a piece of 1/2" PVC exactly 11 inches. Take a regular sheet of 8.5" by 11" paper and roll it onto the tube, using white glue to glue it tightly in place, flush with the PVC on either end.
Take a 3-inch piece of electrical tape and wrap it neatly around one end of the tube, flush with the end. That's it.
You might want to make a few of these if you plan on having more than one person making jets at a time.
