Narrative:

I was doing traffic pattern work. During performing touch and go's upon the 7th landing we had landed on the 1;000 ft markers with the student at the controls. As we rolled out I brought the flaps up and my student went ahead and powered up the airplane simultaneously I saw the nose just immediately drop. I maintained the airplane going down the middle of the runway with the rudder pedals and proceeded to shut down engines and fuel supply to avid any fires. As soon as we brought the airplane to a stop; I exited with my student. My flight was a training flight in preparing my student for his commercial multi-engine check ride. We were practicing maneuvers and local approaches before we initiated traffic pattern. During the traffic pattern we had practiced short field landings and touch and go's. As my perception; I remember specifically the flap indicator showing up; remember the power and still have the picture of the nose just immediately dropping at an instant after the power up. Other information; the airplane skidded right down the centerline of the runway for about 500 ft.
