1. PVC Cannon Project by Brandon Skidgel, Louis Hickman, Hyatt Hopkins, and Brad Ivy

3. - Used gunpowder to 'explode

4. - Then Generates a force of pressure

8. 1912 first industrial development of PVC starts

9. 1920's try to make PVC copolymers

10. 1932 PVC copolymers are put out on shelfs

11. 1936 to 1939 over 400 residences were installed with PVC

12. 1950 through 1960 PVC pipe had a dramatic advance

15. Carburetor Cleaner

16. Spray Paint

17. Propane

18. Ethanol

19. Hydrogen(All of which was just listed is more expensive than Hairspray but more explosive)Ignition-So when you ignite it after spraying it in the back end of the potato cannon it will explode inside of the firing chamber and force the potato out at extraordinary speeds.

20. Solvent Welding Solvent Welding- Solvent welding is the process of joining articles made of thermoplastic resins by applying a solvent capable of softening the surfaces to be joined, and pressing the softened surfaces together. Adhesion is attained by means of evaporation of the solvent, absorption of the solvent into adjacent material and /or polymerization of the solvent cement.

21. BLACK POWDER What is Black Powder- basic black powder is made of 75% potassium nitrate, 15% charcoal, and 10% sulfur. These ingredients are ground to create a uniformly textured powder. How did Black Powder come out-By the 9th century Taoist monks or alchemists searching for an elixir of immortality accidentally stumbled upon gunpowder. What Black Powder is used for- Black Powder is used in all kinds of things in the 19th and 20th century, such as- Cannons, Guns (muskets), and any sort of bomb. (And there were millions of guns and cannons). A simple, commonly cited, chemical equation for the combustion of black powder is 2 KNO3 + S + 3 C -> K2S + N2 + 3 CO2. A more accurate, but simplified, version is 10 KNO3 + 3 S + 8 C -> 2 K2CO3 + 3 K2SO4 + 6 CO2 + 5 N2.

23. Modern rifles are broached

24. ~Broach-a toothed tool toremove material

25. ~Introduced in early 1850s

28. Projectiles Shot-Solid projectile that reliedon kinetic energy to destroy targets --Smoothbore cannon shot= a heavy, solid cannonball --Rifled cannon shot= a solid iron or lead conical shotShell-Explosive projectile that blew up into fragments upon ignition --Smoothbore cannon shell= sphericalshell with timed fuse --Rifled cannon shell= conical shell that used percussion fusesCase-Anti-personnel projectile that sprayeddown iron balls when detonated --Smoothbore cannon case= spherical case that fragmented --Rifled cannon case= conical shell that showered iron or leadballsCanister-Deadliest type of projectile, shot heavy lead balls in shotgun blast --Smoothbore cannon canister= cylindrical canister that destroyed infantry --Rifled cannon canister= double canister was the most deadly
