shots in Dollhouse Burns 1 & 2 were an effect that was  originally conceived for Saving Private Ryan. A tiny pyrotechnic is  attached to a specially machined aluminum plate that sits on the  actors forehead. This is then hidden underneath a prosthetic  appliance made from gelatin. The prosthetic has a hole already cut  out where the bullet hit will be which is then disguised with a soft  wax material that now makes the forehead look natural. A blood tube  and firing lines for the pyrotechnic are hidden in the performers  hair and then on cue the charge is detonated. Although only weak the  tiny charge easily punches a hole in the wax and blood begins to  flow.
