Abstract: Disclosed is a reusable combination corrugated drinking straw and whistle. The drinking straw has an elongated tubular body with a fluid passage running therethrough. The tubular body is manufactured from metal (e.g., stainless steel) and has a plurality of corrugations extending radially outward therefrom. The tubular body is flexible and adapted to be bent so as to enable a user of the corrugated drinking straw to sip a beverage from a cup or the like. The corrugated drinking straw can also be used to produce an audible whistling sound when it is removed from the cup. The whistling sound is achieved when the user blows his breath against a blowing end of the drinking straw that is cut through one of the corrugations that extends radially outward from the tubular body. In this case, the corrugated drinking straw is wider at its blowing end than at the tubular body thereof.

Abstract: A compression tool for compressing and flattening one or both ends of a length of corrugated tubing commonly used for making solar installations. A threaded force-transmitting driver is located within a threaded bore of a force-transmission cylinder. A clamp is disposed in surrounding engagement with the corrugated tubing. Tube retaining lips of the clamp are received between an adjacent pair of corrugatings to hold one end of the corrugated tubing in stationary axial alignment with the force-transmitting driver. A rotational force applied to the threaded force-transmitting driver causes the driver to rotate and move through the threaded bore of the force-transmission cylinder. A compression head at the front of the driver is correspondingly moved towards and into contact with the end of the tubing to compress and flatten the end to prevent a nut from sliding off the tubing.
