Wire a relay as a buzzer. The bigger the better. Use a DC relay and run it
from the same supply as the PIC. Hold it near your circuit in various
orientations.

Operate your circuit in the same area and plugged into the same power
circuits as the biggest, baddest motors or solenoids you can find, and
switch them on and off continuously. Arc welders are also good.
Variable-speed electric drills may also be effective.

Find a piezo spark igniter as for barbecue grills. Operate it near your
circuit. Or for extreme case, connect one side to your circuit.

Once you find a method that produces lots of glitches that affect your
circuit, it's much easier to test the effect of remedial efforts.

Torturing it at the design stage is good, because if it's going out into
the real world, glitches are not a question of IF, they're a question of
WHEN and HOW MANY.
