Introduction: Marble Cannon

By: Ashley Knoch and Rosie Ringer

Step 1: Step 1: Draw and Cut

- Measure one foot of PCV pipe and cut it

- Cut 2 pieces of a wooden dowel, the wooden dowel should be 1/2 inch thick. Measure 16 inches for the height and then cut.

- Measure 8 inches of a "v" shaped wood and cut. This is used to hold the PVC pipe

- Trace the base of the 2 pieces of wooden dowel onto the center of your base

- Cut the straight end of a wire hanger

- Cut a inch of the wooden dowel, separate from the first two

Step 2: Step 2: Drilling

- Drill a hole into a quarter then super glue the quarter on one of the ends of the PVC pipe

- Drill a hole into the center of the 1 inch piece of wooden dowel

- Put the hanger through the wooden dowel's hole and curl on end

- Add the opposite side wooden dowel to the spring

- With the six inch wooden dowels, drill a hole on the outside of each of them

- Use a screw to go through the wooden dowel holes to go into the "v" shaped wood.

- Drill wooden dowels onto the base where you traced them

Step 3: Step 3: Final Steps

- Put spring into the PVC pipe, with the end with the wooden dowel facing the opening and the end of the wire coming through the hole of the quarter

- Add the PVP pipe to the "v" shaped wood and duct tape them together

    I know that our comments have to be nice and all but this instructable made no sense to me. Sorry.

    I do not understand your comment, sorry. Even taking the pictures alone, the idea of the marble cannon and how to build it is absolutely clear.
