Extreme Marshmallow Cannon

• Cut PVC as directed.
• 4 - 1 1/2" x 2 1/4"
• 1 - 1 1/2" x 6 1/2"
• 1 - 1 1/2" x 10"
• 1 - 1 1/2" x 3 7/8"
• 1 - 1" x 2 1/2"
• 1 - 1" x 2"
• 3 - 3/4" x 1 1/2"

• Lay out pieces to make sure you have everything.
• Dry-fitting the entire project is a great idea. Some pieces may need to be sawed down to fit correctly. Lining up the handle can be tricky.
• Draw guide marks. These will help you know when you've pushed the pipe in far enough, and keep it level.
• Picture 2 shows an example of guide marks.

• We will be starting with the bottom and working upwards.
• Remember: PVC glue dries VERY fast.
• You will spread PVC glue around the short pieces and inside the shaped pieces.
• Push and twist together. Make VERY sure that they are all level. If they are not level the rest of the pieces will not fit.
• Quickly after/while inserting the pieces we laid it flat on the table and pushed it flat. This makes sure the whole base is level.

• Using the same method -
• 1 1/2" x 12" one on each side.
• 1 1/2" x 6 1/2" in the center.

• Before and after paint
• Put a 12" piece of PVC into the top. This is where the marshmallows will be loaded and fired.
• You will need to solder wires from the sprinkler valve, switches and extra wire to battery pack. Hide battery in Altoids can.
• One switch is your safety, the other is the firing switch.
• Load marshmallow. Pump with bike pump to 30 PSI. Flip your safety off and fire. The marshmallows will go far, so make sure you have a safe area to shoot them.
• WARNING: Only pump the air cannon to 30PSI. Any more could result in damage to cannon or yourself.
