How to dive and surface a submarine using a Styrofoam block
The original cabin was a Styrofoam cooler. Holes were cut out and replaces with the lenses of old swimming masks hot glued in place. The cabin had two port holes one on top and another in front. After time the Styrofoam cooler was replaced with a 10 gallon fish tank. The Cabin was connected to the frame using twisted wire. During one dive the wire holding the cabin on came lose. The cabin shot to the surface and the frame and operator were dragged to the bottom of the pool.
Cement cinderblocks were used as ballast.
The sea hoarse series of submarines was built in the late 1970’s when I was in high school. They were inspired by a movie “the Neptune factor” made in 1973.Being a youth I’ll describe the craft as I remember it. The sea horse’s were extremely small and built out of odds and ends I managed to scavenge. The submarines only dove in a swimming pool. The Submarine was supplied with air carried by a water hose from a paint air compressor. The pool was unusual in that it was extremely deep, nine feet in the deep end.
