Science cannon result

Cannon Plannng




Procedure


1.) Rip of the plastic material on easch bottle.



2.) Cut off one of the top lid lids of either bottle.



3.) Place 4 pieces of tape in the shooting cannon.



4.) Cut off a piece of the shooting cannon ( about 15%).



5.) Place the lid where the tape is secured at.



6.) Proclaim the angle needed to fire the cannon.



7.) Proclaim the angle needed to combine the cannon.



8.) Cut off the left over peace.



9.) Cut of a side of the stand.



10.) Tape the shooting cannon to the stand.

Results


The The Mini Monster cannon didn't fire a inch, the distance was 0, and it didn't gain the name Mini Monster Flyer. The reason why the cannon didn't fire was because the day we tried to fire it the temperature was cold outside which may have reacted with the firing. The use we had used to fire was ethanol liquid and CO2 which would of helped it fire on a warm day. Even though it didn't fire due to the cold air our cannon melted the ball. The cold air did the same affect for all cannons execept one melted and caught on fire but I believe if we try again on a hotter day the cannon would fire just fine.

The Canister Shot

The Canister Shot cannon is a kind of anti-personnel ammunition used in cannons, that was similar to the grapeshot in which the canister rounds effect is similar to that of a giant shotgun shell.It was used= advent of gunpowder-filling artillery in Western armies frequently on land and sea, the cannon consist of cylinder metal canister filled with round lead or iron balls. The cannon normally packed with sawdust to add more solidity to the mass to prevent the ball from crowding when fired, while canister is dipped in lacquer of beeswax and diluted with turbine to prevent metal rusting. Iron was substituted for large caliber guns while, the end of the canister is closed with with wooden or metal disks, attached to the back was a cloth cartridge bag containing rounds of gunpowder charge to fire; and either sabot wood, metal or similar materials helped the firing accuracy which shot less than 400 yards. The cannon was very useful in the Civil and Napoleonic War as the canister disintegrates the shards and projectiles spread out in a conical formation causing a wide destructive impact.

The Hot Shot

The Hot Shot cannon is a process where a solid iron cannonball is heated red hot in a specially designed wood- or coal-fired furnace. Its then loaded into a muzzle-loading cannon cushion by a substance thickness of wet wads, and fired while still red hot. When this cannon hits it target it will set the target on fire, which was a very successful nearly all the time for base defense against attacks from wooden warships. It was carried by a 2-man litter and in the era of black powder the cannon charges contained in cloth bags, and occasioned much fanfare. It was conveyed to the muzzle as the red-hot projectile that would easily ignite careless handled loose powder.

pbl-cannon cchavis: The Round Shot Cannon

The Round Shot Cannon


The Round Shot cannon is a solid projectile without explosive from fire arms or cannons. The cannon's design is spherical, its diameter is slightly less than the bore of the gun that it's fired from. It was the most popular firearm during the age of sail. being replaced after the invention by Benjamin Robin of the extruded bullet. Round shot has the disadvantages of not being tightly fitted into the bore and to do so would cause jamming in the cannon. This would cause the shot to rattle down the gun barrel and leave the barrel at an angle unless wadding or a discarding sabot is used. The Round Shot cannon has been completely replaced with small arms bullets and by modern shells in artillery.
