A toy sword is disclosed which more accurately replicates the functionality and appearance of fictional light sabers. The sword uses a plurality of telescoping tubes which are fully retractable into the hilt of the sword, and a spring movable between extended and active positions. The spring works in conjunction with a projectile which upon release launches with a smallest diameter tube of the plurality of telescoping tubes and advances same distally away from the hilt. The tubes are telescopingly manufactured so that as the smallest diameter tube reaches the end of its travel, it frictionally engages a distal end of the next smallest diameter tube and in so doing carries that tube distally. In so doing, the entire plurality of tubes is outwardly launched in a cascading fashion. When manually depressed back into the hilt, each of the telescoping tubes is entirely retracted into the hilt, thus not being visible to the user in the retracted position.
