It is rare for a potato cannon to be powerful enough to break the sound barrier, although there are some cases of this happening using specialized designs. The potato cannons used are typically hybrids; but some pneumatic cannons have achieved the feat, either by using a special low-density gas, such as helium , [ 19 ] or high pressures ...
M61 Vulcan, a hydraulically, electrically, or pneumatically driven, six-barrel, air-cooled, electrically fired Gatling-style rotary cannon; M134 Minigun, a six-barrel rotary machine gun with a high rate of fire; Potato cannon, a pipe-based cannon that uses air pressure, or combustion of a flammable gas to fire projectiles, usually potatoes
Archaeological samples of the gun, specifically the hand cannon , have been dated starting from the 13th century. The oldest extant gun whose dating is unequivocal is the Xanadu Gun, so called because it was discovered in the ruins of Xanadu, the Mongol summer palace in Inner Mongolia. The Xanadu Gun is 34.7 cm in length and weighs 6.2 kg.

A particle-beam weapon uses a high-energy beam of atomic or subatomic particles to damage the target by disrupting its atomic and/or molecular structure. A particle-beam weapon is a type of space-based directed-energy weapon, which directs focused energy toward a target using atomic scale particles.
A typical factory-made toy die-cast spud gun. The cap attached to the muzzle converts it into a water pistol. A spud gun or potato gun is a small toy gun used to fire a fragment of potato. To operate, one punctures the surface of a potato with the gun's hollow tip and pries out a small pellet which fits in the muzzle.
The first mention of cannon in Grand Duchy of Moscow chronicles is of tyufyaks, small howitzer-type cannon that fired case-shot, used to defend Moscow against Tokhtamysh Khan in 1382. [43] Cannon co-existed with throwing-machines until the mid-15th century, when they overtook the latter in terms of destructive power. [ 43 ]
An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon.Antimatter weapons are currently too costly and unreliable to be viable in warfare, as producing antimatter is enormously expensive (estimated at US$6 billion for every 100 nanograms), the quantities of antimatter generated are very small, and current ...
