Mateo Despotović is the most successful young rocket launcher in Croatia. His rocket innovation with which he performed at invention exhibitions consists of the following: He innovated lighter rocket material and a propeller that is automatically ejected from the rocket body when the rocket reaches its highest position. That way the rocket falls to the ground longer. In Rocketry, the time a rocket falls from the moment it is fired is measured. Who has a longer time has more points and is more successful.
