Claim:
1. An apparatus comprising: a plurality of coaxially nesting tubes, each having a first end and a second end with a recess on an inside surface of some of the second ends, the plurality of tubes having a stowed position where the first ends are adjacent and an extended position where the first end of an inside tube is directly adjacent the second end of the next adjacent outside tube; a respective spring-loaded retainer located on a first end of each of at least one of the plurality of nesting tubes, each respective retainer having an outer edge coupled to a control aperture wherein the control aperture operates to retain the outer edge coincident with an outside annular edge of the at least one tube in a retracted position of the retainer and wherein a spring of the retainer urges the outer edge radially outwards into the recess of the second end of the next adjacent outside tube; and a rod having an external control button on one end and a tapered tip on the opposing end, the rod is located inside and is also coaxial with the coaxially nesting tubes with the button external to, located on the common axis of the plurality of tubes and extends away from the plurality of tubes on the first end, the rod engages the control aperture of each of the at least one of the plurality of nesting tubes in the stowed position to retain the outer edge of the respective retainers in a retracted position and as the plurality of tubes are extended, the tapered end of the rod disengages the control aperture thereby causing the control button to abruptly pop outwards from the end of the outer most tube.
