Description: First of all, the water rocket is designed when it lands it will start to slow down the speed. Therefore, a parachute is added in front of the water rocket. Secondly, we make use of the accelerometer inside Mirco:bit to create a scoring system to measure the water rocket acceleration through the whole fly process and landing. Moreover, by modifying the Mirco:bit code, we try to create another scoring system for measuring the collision force in order to determine whether the water rocket design is good or not.
