A Zip Gun is any gun that is crudely formed and or improvised. Though there are some multiple shot types, they are usually single shot handguns that may be destroyed by the act of firing. Like a disposable gun. In 2000, a European police agency found a zip gun made from a cell phone. Due to this occurrence, airports have been x-raying cell phones ever since. A zip gun was once even crafted from a large bolt screw!

6. The Trebuchet

The Trebuchet was the Chinese version of the catapult. They were made of wood, but were strong enough to hurl 300 lb. projectiles onto enemy turf. The most common item that got loaded into the Trebuchet was a diseased corpse!

12. The Pigeon-Guided Missile

During World War II, American behavioral scientist, B. F. Skinner attempted to design a pigeon-guided missile. The idea was that a lens would be placed at the front of the missile, projecting an image of the target onto a small screen. Then, a pigeon, trained to recognize the target, would peck the screen. If the pecks were in the center of the screen, the missile would fly straight. If the pecks were to the right or left of the center, the screen would tilt, causing the missile to change course due to a connection between the screen and the flight controls. Three pigeons were to be used, with the flight course being determined by majority rule. This project never got off the ground due to the fact that Skinner could not get anyone to take him seriously, although he did have some success in training the pigeons.

Stay tuned for the rest of the list!

13. The Killer Dolphin

A military dolphin is a dolphin trained for military use. The American military has openly trained dolphins and sea lions for years. They can be trained to rescue lost divers and locate underwater mines. However, there are rumors that they are being trained to do more than that.

16. Who Me?

Who Me? was another non-lethal weapon invented by the US military. It was basically a bad odor weapon intended to humiliate. Who Me? smelled like fecal matter and was distributed among a collection of small atomizers to be discreetly sprayed onto the enemy. The experiment didn't work for a variety of reasons, not least of all due to the fact that the sprayer ended up smelling as bad as the sprayee. There is no conclusive evidence to determine whether or not there was ever a successful attack of Who Me?

17. The Gay Bomb

The Gay Bomb was a non-lethal weapon that contained a combination of chemicals that were said to cause homosexual bahavior in the enemy. Although the bomb was never actually brought to fruition, it was speculated on by a US Air Force research lab.

18. The Puckle Gun

The Puckle Gun was invented in 1718 by James Puckle of London. Mr. Puckle had two designs for his gun. One that shot regular bullets with which to shoot Christians, and one that shot square bullets with which to shoot Muslim Turks. The square bullets were thought to leave behind more painful wounds than the spherical ones.

19. The Pukelight

The Pukelight was actually invented by Homeland Security as a non-lethal weapon. It is an LED flashlight that causes uncontrollable vomiting. The flash puts on a light show that is intended to induce psychophysical symptoms that include vomiting and vertigo.

20. The Car Flamethrower

If you live in South Africa, you can now have a flamethrower installed on your vehicle for relatively cheap (about $655). So far the flamethrower has been allowed by authorities partly due to the fact that South Africa had 13,000 car-jackings in 2008. "The Blaster squirts liquefied gas from a bottle in the automobile's trunk through two nozzles, located under the front doors. The gas is then ignited by an electric spark, with fiery consequences".

22. The Bat Bomb

A bat bomb was a bomb-shaped casing with numerous compartments, each containing a Mexican Free-Tailed Bat (yes, an actual bat) with a small timed incendiary bomb attached. They were intended to be used to start fires in inaccessible places. Bats can actually carry more than their own weight in flight. Also, bats only fly at night, finding a hiding place during the day, making them intelligent weapons. This crazy idea was invented in 1942 by a dental surgeon named Lytle S. Adams, who submitted his idea to the White House. Thereafter it was approved by President Roosevelt.

23. The Kaiten

Kaitens were used during World War II by the Japanese Imperial Navy and were basically torpedos intended to be used as suicide weapons.

Each kaiten was fitted with a 3,000 lb. warhead and were single mission only. They were launched from either a ship or a submerged submarine. A submarine could carry three to six kaitens at a time.

25. Dr. Zippermeyer's Whirlwind Cannon

Dr. Zippermeyer was an Austrian scientist. His Whirlwind Cannon "was meant to produce artificial ‘whirlwinds’ by generating explosions in a combustion chamber and directing them through specially designed nozzles at the target". However, this was not possible at high altitudes.
