Narrative:

In sum: an instructor reports that he briefed a private pilot prior to an aerobatic flight. The parachutes and the aircraft were preflted. The windscreen was crazed, 'though not enough to down the airplane.' after an uneventful takeoff and climb out, the student made a spin to the left. During the second turn of the spin, the windscreen caved in. The student recovered from the spin. The instructor took over the aircraft because the student's face was cut by flying plexiglas. The instructor called bremerton unicom for an ambulance and landed uneventfully.
