I think that the best alcohol you should use is 85 % alcohol or more.You can use 95% or more but you shouldn't put alot in your rocket.Hope that helped.
Duct tape can be used on a bottle rocket to secure components or prevent leaks in the rocket body. It is a strong and versatile adhesive that can help improve the overall performance and safety of the bottle rocket.
You use fins and a nose cone on a bottle rocket because the cone reduces the drag on the rocket, and the fins help stabilize the rocket.
The mass of a rocket bottle will depend on various factors such as the volume of the bottle, desired thrust, and flight characteristics. Typically, a rocket bottle should be lightweight to maximize thrust-to-weight ratio, but also sturdy enough to withstand the pressure during launch and flight. It's best to consult with a rocketry expert or use simulation software to determine the optimal mass for your specific rocket design.
Yes if you use compressed air inside the rocket. Or you can use agitated methanol and a flame for thrust like a whoosh rocket.
It is not recommended to use another type of liquid for a bottle rocket besides water. Water is the safest and most commonly used liquid for bottle rockets as it provides the necessary weight and propulsion for the rocket to launch. Using other liquids could be dangerous or ineffective.
You need 17 bottles. Thank you for your cooperation.
The amount of ballast used in a bottle rocket typically depends on the size of the bottle and the desired flight characteristics. A good starting point is to use around 10-20% of the bottle's total weight in ballast. It's important to experiment, as too much ballast can hinder flight, while too little may result in instability. Adjust the ballast based on test flights to achieve optimal performance.
Water, an empty plastic bottle and an air pump.
The best way to store and dispense alcohol in a mixer bottle is to keep the bottle tightly sealed when not in use to prevent evaporation and contamination. When dispensing, pour the alcohol slowly to avoid spills and measure accurately for consistent mixing.
I like to put them on the lowest section, i feel this gives more stability.
A craft knife, a ruler, and a glue bottle is all I ever use.
Possibly a rocket.
