Science cannon presentation

  1. 1. PVC Pipes ( Polyvinyl chloride )
  2. 2. P V C   P I P I N G Most PVC pipes are used in projects for the home. Landscaping, piping, and of course cannons :D. It covers over 50% in distributing water in the country and in the sewer system as well. Now while we used this material, those in the Mid-1800's had no access to this. Piping has many uses. It brings us that, um, VERY delicious tap water. It removes our leftovers from our homes. It also moves air and gas throughout the city. There are many different types of pipes. PVC in particular is the 3rd most produced plastic.
  3. 3. P   P r    V o   C p e   P r    i t    p i    i e   n s   g   o f <ul><li>Polyvinyl chloride or PVC has many Properties.It wa first manufactured in the mid-1830's. However since it had no use it was forogtten about until the 1920's. By the 1930's PVC pipes wereused in transporting. </li></ul>PVC is created through a chemical process where  vinyl and chloride are bonded. Unlike other polymers, creating PVC requires less petroleum.
  4. 4. Cannon Types Muzzleloaded & Mortars                                                      o  
  5. 5. Types of cannons. In the civil war the only type of cannons avalible were front (or muzzleloaded) and mortars.
  6. 6. Propellent For PotatoCannons   <ul><li>  </li></ul><ul><li>  </li></ul>
  7. 7. The propellent we used for our cannons was hairspray (aqua net). We put a certain amount then ignite it.
  8. 8. Black Powder
  9. 9. <ul><li>Black Powder, also known as gun powder, originated in China around the tenth century, and was used for fireworks and signals. It is a mixture of saltpeter, sulfur, and charcoal. Further developments were made later on, such as: The safety fuse in 1831, dynamite in 1867, and smokeless powder in 1888. </li></ul>Black Powder
  10. 10. Solvent welding
  11. 11. Solvent Welding <ul><li>Solvent welding is when a solvent is used to temporarily melt and fuse plastics. It is most commonly used with PVC and ABS pipes. First, the solvent is added the to both pipes you want to &quot;glue&quot;, then the pipes are put together and fuse within 24 hours. </li></ul>
  12. 12. How Cannons Work      :D <ul><li>  </li></ul>
  13. 13. How Cannons Work :D A cannon in the Civil War was loaded with a cartridge of Black(gun) powder, the ammount depending on the distance(and size) of the target, also the size and projectile. In order to get the ammunition to the bottom of the tube a pushed into the tube, breach, with a rammer (A long stick). After the charge and the ammunition are tightly packed, a steel wire (using friction) would light a spark, igniting the gunpowder.
  14. 14. The Projectiles of These Awesome Things! VS.
  15. 15. The Projectiles <ul><li>Back then, in the South, Industry wasn't their calling....So when they ran out of regular ammunition, THEY IMPROVISED! :D </li></ul><ul><li>Instead of using cannonballs, they even used bombs! Now, they had, split shots(where they would basically use a scizzoring motion to cut through defenses) Chain shots(where two smaller cannon balls were connected by a chain, put in a temp. cannister, and fired) and SO MUCH MOOORREE!!!!!1 </li></ul>
  16. 16. THE END
