PVC Blowgun

• 1). Smooth the inside of the openings at each end of the PVC pipe to remove any burrs or other projections.
  
  
• 2). Apply a 1/2-inch wide band of PVC cement around the outside of one end of the PVC pipe. Attach the PVC reducer coupling to the end of the pipe by twisting it into place. Allow to dry thoroughly, according to the manufacturer's recommendations.
  
  
• 3). Insert a wine cork into the PVC pipe through the reducer coupling mouthpiece. Push the wine cork a short distance into the pipe, using the wooden dowel rod as a plunger.
  
  
• 4). Place your mouth into the reducer coupling mouth piece and blow with a strong, forceful burst of breath.
  
  
• 5). Experiment until you identify the best depth to insert the cork before blowing. Make a mark on the dowel rod plunger for future reference.
