Do You Know The Potato Cannon? - Quiz

A Potato Cannon is a toy gun that engages air pressure to propel weapons into projectile motion at high speed. The propelling force could also be from combustion of a flammable gas.


Questions and Answers
  • 1. 

    A potato cannon can also be called 

    • A.

      Potato shooter

    • B.

      Spud shooter

    • C.

      Spud gun

    • D.

      Spud cannon

    Correct Answer
    C. Spud gun
    Explanation
    The correct answer is "Spud gun." A potato cannon is a device that launches potatoes using compressed air or combustion. It is commonly referred to as a spud gun because it shoots spuds (potatoes). The terms "potato shooter," "spud shooter," and "spud cannon" are also used to describe this type of weapon. However, "Spud gun" is the most commonly used and recognized term for this device.

    Rate this question:

  • 2. 

    Potato cannons were first used in the 

    • A.

      World War 1

    • B.

      World War 2

    • C.

      American Civil War

    • D.

      Napoleon War

    Correct Answer
    B. World War 2
    Explanation
    Potato cannons were not used in World War 1, the American Civil War, or the Napoleon War. However, they were first used in World War 2. This war saw the development and use of various unconventional weapons, including potato cannons. These cannons were homemade devices that used compressed air or combustion to launch potatoes at high speeds. They were used by both military forces and civilians for various purposes, such as training exercises, entertainment, and even as makeshift weapons in some cases.

    Rate this question:

  • 3. 

    The following are ways by which weapons are propelled from potato cannons except 

    • A.

      Combustion launcher

    • B.

      Pneumatic launcher

    • C.

      Dry ice bomb

    • D.

      Bomb launcher

    Correct Answer
    D. Bomb launcher
    Explanation
    The given options list different ways by which weapons are propelled from potato cannons. Combustion launcher and pneumatic launcher are commonly used methods where combustion or compressed air is used to propel the weapon. Dry ice bomb is another method where the explosive force of dry ice is utilized. However, bomb launcher is not a method commonly used to propel weapons from potato cannons. Therefore, the correct answer is bomb launcher.

    Rate this question:

  • 4. 

    The following are elements of combustion launchers except 

    • A.

      Fuel system

    • B.

      Combustion gauge

    • C.

      Combustion chamber

    • D.

      Ignition source

    Correct Answer
    B. Combustion gauge
    Explanation
    Combustion gauge is not an element of combustion launchers because it does not play a role in the actual combustion process. The fuel system is responsible for delivering the fuel to the combustion chamber, the combustion chamber is where the fuel is burned, and the ignition source is used to initiate the combustion process. However, a combustion gauge is not necessary for the functioning of a combustion launcher as it does not contribute to the combustion process itself.

    Rate this question:

  • 5. 

    The following are components of pneumatic launchers except 

    • A.

      Filling Valve

    • B.

      Pressure release gauge

    • C.

      Air chamber

    • D.

      Barrel

    Correct Answer
    B. Pressure release gauge
    Explanation
    The pressure release gauge is not a component of pneumatic launchers. It is used to measure and display the pressure inside the air chamber or barrel, but it is not a physical component of the launcher itself. The other components listed, such as the filling valve, air chamber, and barrel, are all necessary parts of a pneumatic launcher.

    Hybrid launchers consist of how many elements?

    • A.

      5

    • B.

      6

    • C.

      7

    • D.

      8

    Correct Answer
    C. 7
    Explanation
    Hybrid launchers consist of 7 elements.

    Rate this question:

  • 7. 

    Which of the following is not an element of hybrid launchers? 

    • A.

      Barrel

    • B.

      Air filling valve

    • C.

      Combustion chamber

    • D.

      Ignition knob

    Correct Answer
    D. Ignition knob
    Explanation
    The ignition knob is not an element of hybrid launchers. Hybrid launchers typically consist of a barrel, air filling valve, and a combustion chamber. The ignition knob is not necessary for the functioning of a hybrid launcher as it is used to initiate the ignition process, which is not relevant in the context of hybrid launchers.

    Vacumm cannons are different because they engage 

    • A.

      Minimal pressure

    • B.

      Maximum pressure

    • C.

      Negative pressure

    • D.

      No pressure

    Correct Answer
    C. Negative pressure
    Explanation
    Vacuum cannons are different because they engage negative pressure. This means that instead of creating pressure to propel an object, vacuum cannons create a vacuum or an area of low pressure. This difference allows vacuum cannons to launch objects using suction rather than force, making them unique compared to cannons that rely on high pressure to propel projectiles.

    The following are metals used in potato cannons except 

    • A.

      Copper

    • B.

      Aluminium

    • C.

      Steel

    • D.

      Zinc

    Correct Answer
    D. Zinc
    Explanation
    Zinc is not used in potato cannons because it is a relatively soft metal and may not withstand the pressure and force generated during the explosion. Copper, aluminium, and steel are commonly used in potato cannons due to their strength and durability.

  • 10. 

    The following are types of valves used in pneumatic cannons except 

    • A.

      Piston valve

    • B.

      Chain valve

    • C.

      Diaphragm valve

    • D.

      Burst disk valve

    Correct Answer
    B. Chain valve
    Explanation
    The given answer, "Chain valve," is correct because it is the only type of valve listed that is not commonly used in pneumatic cannons. Piston valves, diaphragm valves, and burst disk valves are all commonly used in pneumatic cannons to control the flow of air or gas. However, a chain valve is not typically used in this context.
