[Topic] Wallace (Deep Sea) [Question] How are the waves made? How deep are they? [Answer] 
The waves are made using the hot wire foam cutter, with the medium width blade from the kit (between 1/4" and 1/2"). Use the foam cutter to make a shallow cut into the foam. This cut will be about 1/4" deep. Note that the wave cuts are covered with paper.
