This is a demonstration of a simple airflap system for releasing a parachute on a water rocket. The big airflap releases the cone which contains the parachute. The rubber has 2 functions at the same time : holding the cone in place AND pulling the big airflap. The little airflap is pulled down at launch, thus releasing the big airflap. The wind holds the big airflap down. When rocket has no more speed, the big airflap goes up, and the rubber is released from the pin on the airflap, thus releasing the cone and the parachute. (the parachute is not attached yet, so in this clip, it simply falls off ...)
