An apparatus including a plurality of coaxially nested tubes, a respective spring-loaded retainer located on a first end of some tubes, each retainer having an outer edge wherein release of the control aperture causes a spring of the retainer to urge the outer edge radially outwards into the recess of the second end of the next adjacent outside tube; and a control rod having a button on one end and a tapered tip on the opposing end, the control rod engages the control aperture of each of the tubes in the stowed position to retain the outer edge of the respective retainers in the retracted position and as the plurality of tubes are extended, the tapered end of the control rod disengages the control aperture thereby causing the button to abruptly pop outwards from the marginal edge of the outer most tube.
