What materials can be used to create a mini rocket bottle prototype?

• Plastic bottle, cardboard fins, cork or rubber stopper, needle, tape, water, air pressure

• Aluminum can, paper fins, plastic cap, string, glue, soda, mentos

• Glass bottle, metal fins, plastic stopper, straw, glue, vinegar, baking soda

• Wooden box, paper wings, metal lid, string, nails, oil, matches

Explain the importance of aerodynamics in designing a mini rocket bottle prototype.

• Aerodynamics is important for stability, speed, and efficiency of the rocket during flight.

• Aerodynamics is essential for underwater rocket design

• Aerodynamics only affects the appearance of the rocket

• Aerodynamics has no impact on rocket performance

How can the shape of the mini rocket bottle affect its flight trajectory?

• The shape of the mini rocket bottle can affect its flight trajectory by influencing aerodynamics.

• The shape of the mini rocket bottle determines the size of the explosion upon landing.

• The shape of the mini rocket bottle affects the color of the flames during flight.

• The shape of the mini rocket bottle has no impact on its flight trajectory.

Discuss the role of fins in stabilizing a mini rocket bottle during flight.

• Fins increase the weight of the rocket bottle, causing instability.

• Fins are detachable and serve no purpose during flight.

• Fins stabilize the mini rocket bottle by creating drag and aerodynamic stability.

• Fins are used for decoration purposes only.

What are the key factors to consider when designing the nozzle of a mini rocket bottle prototype?

• Nozzle color, weight, and texture

• Launch location, weather conditions, and time of day

• Nozzle shape, material durability, size, and angle

• Rocket fuel type, ignition system, and payload capacity

Why is it important to conduct test launches when developing a mini rocket bottle prototype?

• Mini rocket bottles do not require testing

• Test launches are unnecessary and waste resources

• Test launches help ensure functionality, safety, and performance of the prototype under realistic conditions.

• Testing can be done virtually without physical launches

Describe the process of calculating the optimal amount of water and air pressure for a mini rocket bottle launch.

• Guess the water volume and air pressure randomly without any calculations

• Consult a fortune teller to predict the optimal water and air pressure

• Use trial and error to determine the water volume and air pressure

• Calculate the ideal water volume based on bottle size and desired launch height, then determine the corresponding air pressure using physics principles.

How can the weight distribution of a mini rocket bottle impact its performance?

• The weight distribution can improve the rocket's speed

• The weight distribution has no impact on the rocket's performance

• The weight distribution only affects the rocket's color

• The weight distribution can impact the rocket's stability, trajectory, and fuel consumption.

Explain the concept of thrust-to-weight ratio and its significance in mini rocket bottle design.

• Thrust-to-weight ratio is not relevant in mini rocket bottle design.

• A lower thrust-to-weight ratio indicates better acceleration and performance of the rocket.

• Thrust-to-weight ratio is the ratio of the thrust produced by the rocket to the weight of the rocket. It is significant in mini rocket bottle design as a higher thrust-to-weight ratio indicates better acceleration and performance of the rocket. This ratio helps determine if the rocket will be able to overcome gravity and lift off effectively.

• Thrust-to-weight ratio is the ratio of the weight of the rocket to the thrust produced by the rocket.

What safety precautions should be taken when launching a mini rocket bottle prototype?

• Wear a helmet

• Launch indoors

• Ignore safety guidelines

• Wear safety goggles, launch in open outdoor area, ensure rocket stability, have fire extinguisher nearby, follow local laws and regulations.
