Pot rocket: Cannon shoots pot across border

WPIX -- MacGyver has apparently gone to work for the drug lords.

The Mexican Federalis have confiscated a powerful Mexican marijuana cannon that was apparently used to fire packages of weed across the Tex-Mex border.

The cannon in the back of a truck is made out of a plastic pipe, a metal tank and an old car engine. It can send pot-packed canisters up to 30 pounds hurling over the border fence.
