A water bottle rocket consists of an intact two-liter soda bottle at the bottom to hold water and air under pressure, optionally, a second soda bottle for greater length and stability, weight at the top, and fins at the bottom the weight and fins are for stability, like an arrow for a rocket to be stable the center of mass (the balance point) should. You have to figure out how much momentum each little increment of expelled water gives to the remaining rocket, whose mass is the rocket mass plus the remaining water mass the change in momentum of the remaining rocket is equal to the speed s of the ejected mass in the frame of the rocket i don't quite know how to calculate s because i'm not.
