A bottle rocket launcher is provided for rockets constructed for educational and entertainment purposes out of synthetic resin bottles used primarily for soft drinks. The rocket launcher includes a bottle plug for filling the bottle rocket with compressed gas such as air and guiding it as it exits the launcher, a release mechanism for initially retaining and then selectively releasing the rocket adjacent its nozzle, and a base. The release mechanism provides multiple hooks which grab a rim adjacent the nozzle, and selectively and simultaneously releases each of the hooks, whereby the upward force applied by the compressed gas against the liquid causes the hooks to slide off of the rim and permits the rocket to lift off of the launcher. The bottle plug is releasably connected to the release mechanism, while a gas delivery conduit remains connected to the bottle plug for inhibiting spillage of liquid from the bottle rocket until the bottle rocket is secured to the release mechanism and filled with compressed gas prior to launch.
