We experimentally studied the propagation of coupled fluid stress waves and tube flexural waves generated through projectile impact along the axis of a water-filled tube. We tested mild steel tubes, 38–40 mm inner diameter and wall thicknesses of 0.8 mm, 6.4 mm, and 12.7 mm. A steel impactor was accelerated using an air cannon and struck a polycarbonate buffer placed on top of the water surface...

The sampling tube, an open-ended polyethylene feeding catheter sterilised by the manufacturer, is filled with sterile distilled water. A 2.0% suspension of agar in distilled water is prepared and enough cochineal to colour the solution is added. This is autoclaved at 44N/10 min to dissolve and sterilise the agar. When the solution has cooled to 60°C an 8 cm length of the coloured agar solution ...
