Water Rocket Project

The design that I have made for my rocket is tall and somewhat fat because I used two 2 liter soda bottles for the entire rocket. Also, I used two 2.63 liter tea bottles to combine the two 2 liter soda bottles and to make the outer shell to surround the egg and the placement of the parachute. It is quite simple, with very few to no decorations such as the fins because I want to keep the weight of the rocket the same and not add even more mass into it. Adding a parachute to the rocket would help its landing more secure and safer because it would slow down as it goes down from the sky, which would increase the friction of the rocket slowly. Putting a lot of cotton to surround the egg and putting it inside would make the egg more secure because there won’t be any hazard once it causes an impact when it hits the ground. Also, it would decrease the area of the egg, which would decrease the pressure on the egg a little. I chose to increase the mass between two bottles because I want the bottle to land from its bottom and vertically, not from its top nor move sideways when landing. I decided to make a parachute to increase the friction slowly as it goes down, which is the thermal energy from the air to make the rocket land safely and smoothly. To decrease the pressure on the egg, I decided to put cotton to decrease the force and lower the chance of cracking. For the force to be affected, the acceleration must be lower or higher than the mass of an object. To decrease the pressure of the egg, I increase the area of the force of the egg by putting it inside the bottle to have more space on its side. I chose the fins to be made from cardboard because I didn’t want to have an interference with the mass that was already added and the accelera...

.../Area), there’s no modifications that I would make to help the egg survive next time because in the design that I currently have, the egg finally survived on the second try of the launch and rebuilding of the rocket. If the egg never survive and cracked, some modifications that I would make to help the egg survive next time are to make a more sturdy outer shell that surrounds the egg while it is inside the bottle and even more cotton and better materials to use for the cushioning for the egg. These modifications would help the egg to survive because if the outer shell that surrounds the egg as it sits inside the bottle is sturdier than before and stronger, and then the impact of the ground would not have a huge effect on the outer shell. If the outer shell is strong, the egg will not feel any impact as it drops to the ground and it will not break or do any damages.
