This is a capsule for my water bottle rocket which this is just a prototype for the capsule and i dont know how i can make the parachute deploy. There is a tube inside the whole as wide as the hole and im expecting to fit the parachute inside the tube. The problem is how to deploy it without crazy mechanics because its a water rocket. The prototype uses a normal paper which looks ugly but the real one will be used with oily paper. The cap can be automatically open by air but it is not strong enough to pull the parachute out and neither does the capsule itself. Please let me knos if you have any ideas of how to do this
