One of the funniest things you can do with a stun gun is to use it as an igniter for a potato cannon. That is, if you can find one.

The good news is that there are plenty of devices to help you get the job done. For example, there are stun guns that attach to a key chain so you can carry them on your wrist at all times.

Stun Guns

Using a stun gun as a potato cannon igniter is an interesting idea. It’s not a new idea, but it has recently been tested in a number of television shows and movies, including Aliens in the Attic, MythBusters, Bully, Iron Man 3, and House, M.D.

The basic idea is simple: a conductive liquid is stored in one container, and compressed gas is discharged through it at another. This creates a high voltage shock to the person who receives the conductive liquid from the discharge point.

This can be done in a variety of ways, and is particularly common for air cannons (also known as “air cannons”), which use a mixture of compressed gas and a fuel. The pressure behind the cannons can be very high, and the recoil can be very severe.

Some spud guns use dry ice, rather than air, to provide the necessary pressure. This works by sublimating the dry ice, which then produces substantial pressure in the bottle. This pressure can be up to 800 psi (5.5 MPa), and it’s possible to release the pressure by opening a valve.


Spud guns are devices that fire a projectile (typically a potato) at high velocity. They are often used for fun and recreational purposes, but can also be useful in agriculture or riot control.

The most basic type of spud gun is a combustion gun that uses the combustion of gases at atmospheric pressure to propel the projectile. Another more powerful type is a pneumatic cannon which uses pressurized air to launch the projectile.

A hybrid combines the principles of both types to produce the most power from a given chamber volume. Typically this is done by using a fuel and air mixture at twice the atmospheric pressure in the combustion chamber, although higher ratios are possible.

Spud guns are commonly made with improvised materials and construction, and therefore present safety risks if not properly constructed or used. They are often outlawed or restricted in some jurisdictions. For this reason, spud gun enthusiasts should follow normal firearm safety rules when handling their device.


A stun gun is a tool that delivers a low-amplitude shock that can disable an attacker for up to 30 minutes. The energy passes from the stun gun to the intruder, disorienting them and causing them to lose their balance and muscle control.

Stun guns are typically used to repel and startle a potential attacker, not to kill them. They’re also useful in self-defense, especially for women and children.

Many spud guns use an ignition device — often a grill starter or stun gun — to create a spark inside the barrel. This spark ignites the fuel, causing an explosion.

Spud guns can be made from a variety of materials. For a simple version, you can use a PVC pipe and a potato.

For a more advanced design, you can use compressed air or combustion to propel the potato. These cannons are typically much more powerful than traditional spud guns and can launch the potatoes over a long distance.


When using a stun gun as a potato cannon igniter, there are certain safety precautions that you should follow. These include ensuring that the stun gun is unplugged before firing it and avoiding direct contact with the metal wire after each use.

As a rule, you should also avoid allowing the stun gun to stay open for long periods of time. This can cause it to overheat and potentially damage the wire.

The stun gun is a popular tool for self-defense and a fun way to pass the time. However, it is important to be aware of the dangers of its electric arc and the potential for electrocution when using it as an igniter.
