He needn't tell your friend ahead of time. He can just do that, and then tell your friend, "now we are flying as if we lost all engine power." When your friend sees how much the plane glides, he'll overcome what is likely his greatest fear, which is plummeting to earth out of control.
I suggest the CFI not perform any spin maneuvers.
Just don't explain glide ratio's and lift to drag ratios. A 747 will glide further than the Cessna as it has a glide ration of 18:1 vs the Cessna's 10:1 (Miles/for every 1 mile of vertical height). The problem is the Lift to drag ratio. The 747 will hit the ground waaaay before the Cessna because it has far more drag.
