My science fair project is about what different types of flammable gasses will make the potato shot further than it would with hair spray out of a potato cannon. I will have to make the potato cannon then test out the different gasses; this will allow me to get more variables, but there will also be more controls in the project. A control in my potato cannon is how long I have to spray the gasses inside the potato cannon. When doing my research I read an article that said not to use any other types of gasses or spray liquid other than hair spray so I have another control because of how dangerous it could be, so by making the ignition longer I will be a safe distance away. Due to the history and past experiments along with the procedures of making the potato cannon, my project will illustrate the concepts of physics. The cannon has been around for hundreds of years. First used in China the cannon was a gunpowder …show more content…
After you follow these steps you will have to open the end plug and spray hair spray inside the combustion chamber for around two seconds; then you have to screw the end plug onto the combustion chamber as soon as possible. Next you have to put your potato into the barrel, but it is not supposed to fit, the reason is because if put the whole potato inside it would have all the force go around the potato. So by having to shove the potato in the barrel this will allow no air or force to pass by the potato. After all the test runs I was going to see what other types of flammable gasses would work and if they would work better than the hair spray. Past experiments have taught me that you should not use any other type of gas or liquid spray than hair spray. Most of the experiments that I found on various websites were not for a science fair project. They weren't even for science they were for fun, but I did learn that a potato cannon is really dangerous no matter if you use gunpowder, compressed air, or hair
Weapons have been around from the Neanderthals of the post-ice age, to the Taliban in Afghanistan. Rocks became knives, sticks became spears, and bayonets became AK-47’s. The technology from the French and Indian War was revolutionized and manufactured by the newly opened weaponry companies. Colt and Winchester had a new end of the market during the times of conflict in the United States.
The way in which the gas is let out is that there is a needle in a valve in the top of the tank and when the tank is screwed into the paintball marker the needle gets pressed down and the entire system becomes pressurized and is ready to be fired. Then when the gun is cocked and the trigger is pulled the bolt is pushed forward, accelerated by the force of the C02 acting behind it and pushes the paintball out. Then the bolt comes back into the read position and the C02 is no longer flowing and is again pushing against the bolt.
The gun was a hand-crank-operated weapon with six barrels revolving around a central shaft. Having a gun that revolves was very difficult because the barrels would not always line up correctly when being fired. The original gun was actually designed to fire the standard military issue paper cartridge of the day, .58 caliber. A .58 caliber bullet has a diameter of an inch and is capable of damaging anything it hits. The paper cartridge was placed inside a steel or brass chamber with a percussion nipple on the back end just like the muzzle loading rifles and pistols of there time.
The ignition device of a spud gun is simply put the spark generator that causes the combustion of the fuel in the firing chamber. This device is usually a charcoal grill lighter. The button on the sparker is depressed and a spark arcs across a wire lead and a ground wire. The grill sparker is installed in to the back of the firing chamber by means of threading, epoxy, and bolts. This sparker becomes a projectile if it is not well seated in the end cap of the firing chamber. It must be held firmly in place withstanding any pressure produced by the fuels being burned in the chamber. This type or igniter will work in most conditions including when it becomes wet with fuel.
Method: [IMAGE] Equipment needed: Ruler Measuring Cylinder Scalpel Tongs Pipette Thermometer Tri-pod Stop-clock Gauze Delivery Tube Bunsen Burner Beaker Matches/Lighter Potato Hydrogen Peroxide Solution (20%) Water Lead Nitrate The skin of the potato was removed using a scalpel and then cut into 1cm², using a ruler to measure the size of each cube, four cubes are required for each experiment, and therefore at least 36 cubes are required for the full experiment to take place. Fill a beaker half way with water, and place a thermometer in the water. Allow the thermometer to warm to room temperature to gather an accurate reading, and measure the temperature, using the thermometer. A measuring cylinder was used to put 10ml of Hydrogen Peroxide Solution into a
Soldiers were ordered to load and they would take a cartridge and rip it open. Sometimes they would open them with their own teeth. After they opened it, they poured powder into the pan of the firing mechanism to fill it up. They would pour the main portion of the powder down into the barrel, and then they folded paper and put it into the barrel and dropped the ball at the top. They used the ramrod under the barrel of the musket to...
This was the self contained brass cartridge. It contained an ignition source called a primer, an amount of powder and a bullet. Early cartridge guns were converted percussion rifles. The first repeating rifles were the Henry and Spencer, the Henry had a fifteen shot internal magazine and the Spencer a seven round removable magazine this meant multiple could be carried. Repeaters were not limited to rifles though handguns such as the famous Colt Single Action Army were a common favorite among both civilians and military personnel. The industrial revolution boosted the firearms industry. It allowed gunsmiths who formerly would cut rifling and make parts by hand using saws and files to now use vertical mills and lathes to improve both output and precision. Barrels became easier to rifle and take to size using lathes and mills allowed sights to be manufactured much easier. The next major evolutionary step in the firearms industry was the bolt action rifle. A bolt action provides a tighter seal at the breach than other actions allowing higher pressure cartridges and a farther effective range do to increased velocity The first bolt action used by the U.S. military was the Krag-Jorgensen a Norwegian rifle with a internal side loading magazine. It was thought by many that the Krag was was an exceptional piece of equipment but during the Spanish - American War it was proved otherwise. Spaniards armed with German Mausers a rifle with a

“Volley Guns” (Chivers, 2010, p.26) or also known as “Organ Guns” (Ellis, 1975, p.10) were first attempts at increasing firepower by adding several barrels at the firing itself, rather than simply attempting to increase the rate of fire. “Gunsmiths had long ago learned to place barrels side by side on frames to create firearms capable of discharging projectiles in rapid succession. These unwieldy devices, or volley guns, were capable in theory of blasting a hole in a line of advancing soldiers” (Chivers, 2010, p.26). An example of such weapons can be seen on July 28, 1835 when Giuseppe Fieshi unleashed terror on King Louis-Phillipe in Paris, France. He fired his 25 barrel “volley gun”, killing 18 of the king's entourage and grazing the King's skull. The weapon was ineffective however. Four of the barrels failed and another four ruptured. Two other barrels had exploded inside, grievously wounding Giuseppe. (Chivers, 2010, p. 27)
However, there was one flaw. If we fired the cannon too fast, the carbon in the chamber builds up and will not let the oxygen get back into the chamber to be reignited. If
