Watertight
Bill starts making a watertight collar for his diving helmet. It is a sandwich of neoprene held between two metal rings. This will let air out but will allow little or no water in. Tinker time is frantic and the Rusty Regiment cover their diving helmet with lead to give it neutral buoyancy. The Supermodels give their grabber extra bite with some fangs.
