Bottle Rocket Experiment

Professor Rebecca introduces a challenge to build a vehicle powered by Mentos and soda. The video provides a list of materials and design ideas, including using household items like popsicle sticks and fidget spinners. Instructions are given on building and powering the vehicle, emphasizing the importance of creating a nozzle for speed. Guidelines for conducting the experiment are provided, including finding a level surface and measuring the distance traveled. The video concludes with a scientific explanation of the reaction and encouragement to try the experiment.

What is the primary purpose of the experiment described in the video?

• To create a Mentos and soda bottle rocket car

• To build a model airplane

• To design a solar-powered vehicle

• To construct a water balloon launcher

Which of the following items is NOT mentioned as a potential material for building the rocket car?

• Metal rods

• Ketchup container lids

• Popsicle sticks

• Fidget spinners

What is one way to increase the speed of the rocket car?

• Attach a sail to the car

• Add more wheels

• Drill a small hole in the bottle lid

• Use a larger soda bottle

What should you do to ensure the vehicle starts correctly?

• Drop the Mentos into the bottle and let go

• Use a remote control to start it

• Tilt the bottle at an angle

• Push it over the start line

What is the role of the Mentos in the experiment?

• To serve as a weight for the car

• To create nucleation points that release gas

• To provide a source of energy through combustion

• To act as wheels for the car

What is the main scientific principle that makes the rocket car move?

• Nucleation process

• Friction reduction

• Magnetic force

• Gravitational pull

What is the final step in measuring the success of the experiment?

• Weighing the car before and after the experiment

• Counting the number of Mentos used

• Measuring the distance traveled by the car

• Calculating the speed of the car
