The speed tube mounted on the boat.
To make: | Use two clear tubes. A long tube: 8mm outer and 6mm inner diameter of 25cm long and a short tube: 6mm outer and 4mm inner diameter of 2.5cm long. Glue the short tube with waterproof glue in the long tube. Secure the tube with duct tape under the stern of the boat. The short tube should protrude above the canvas. The narrower inner tube allows the fountain to spray higher and respond better to speed fluctuations. |
