Group plans…

So far our group has confirmed that we are going to attempt to create a Pneumatic Cannon.  This group consists of Me, Palmer, TJ, and Kaitlyn.  So far we have written out a list of materials and a rough blue print on the construction of our cannon. We have also taken a trip to Ace and have located all the materials and have a rough estimate of our project costing in the neighborhood of $100 to $150, hopefully less if possible. Along with this group I am also still helping finish the duct taping of Whitni and Abby’s boat, I will be filming their trial in the pool, and I am planning on bringing a paddle so they are able to row their boat.

These are our basic plans and materials for our cannon-


  1. 1″ pipe (short for use as nipples)
  2. 1 1/2″ pipe
  3. 1 1/2″ coupling
  4. 1 1/2″ x 1″ reducing bushing
  5. 2″ pipe
  6. 2″ street elbows (male and female connections)
  7. 2″ endcap
  8. 2″ x  1″ reducing bushing
  9. 1″ to male thread (2)
  10. Tire valve
  11. 1″ ball valve
  12. Large block of wood and tire strap for spacer
  13. PVC cement and primer
  14. Drill
  15. Saw
  16. Pressure gauge
  17. Air compresser
  • We need to make sure we buy pressure rated PVC
  • We need to make sure we let set at least 24 hours after gluing to make sure the glue sets
  • Our projectile possibilities at this point include: potato, baseball, or tennis ball
  • We still need to decide an air pressure to use for our cannon

This is what we are aiming for with our cannon design:
