Step by Step Tutorial on how to build a powerful Vortex Cannon.
Plastic Shower Liner
Bolts and handle(Optional)
Step 1: First Cut a Whole on the Top of the Bucket Leaving 1.5 Inches on All Sides
Step 2: Then Sand the Inside Smoothing Out Any Rough Edges
Step 3: Adding a Handle (optional)
I used three large bolts to connect a piece of wood which I could connect a makeshift handle to. After completing the project, however, I realized that it is much more effective to hold it by your waist, making the handle not needed.
