About an actual ballistic knife: The spring in these knives is powerful enough to propel the blade to about 6 meters (about 18 feet) or more at 63 km/h (39 mph). They were not without drawbacks however: Because the projectile blade had no aerodynamic or gyroscopic stabilization, it was only accurate...

The volume of a cylinder is calculated with the equation V=Pi*R^2*H, V is volume, R is radius, and H is height. Do that for the inside measurement of the pvc and you have the approximate volume. To be more specific, the volume of a sphere is 4/3*Pi*R^3, so use that to figure out the volume around th...
