Marble Cannon Project

Josh and Brandon

Our materials were purchased from Ace Hardware.

This is the start of the construction process where we started building the shape of our cannon.

In our trials, we used the highest launch angle and the third highest launch angle. The highest launch angle is 49 degrees. The third highest launch angle is 40 degrees. We used the highest launch angle from 2 meters and from 2.5 meters away. We used the third highest launch angle from 3 meters away.

Cut holes on both sides of the PVC pipe to where wood can slide down it.

The Spring produces the force that shoots the marble. Rest the pipe with the spring on the selected launch angle.

Slip the wood segment through the top of the PVC pipe and directly on top of the spring.
