Pump Rocket Mini Replacement Rockets 8 Pack Extra Rockets for use with all Geospace PUMP ROCKET MINI launchers. Adds more fun since kids can shoot more rockets before having to go retrieve the fired rockets. Replacement rockets are also helpful in case original rocket gets stuck on the roof or in a tree. Soft foam construction (including super-soft tip) means no ouchies. These MINI-sized rockets can be used interchangeably with JR-sized Pump Rocket items.
