Bathysphere In Clay July 7, 2011

Bathysphere made of clay.

Bathysphere made of clay.

Her sphere is a bit untrue and the windows a bit googly-eyed, but she’s sea worthy.  She’s tested for pressures of 2 feet of water or 0.867 pounds per square inch (the depth of my fish tank.)    The original bathysphere was a steel ball with three windows (one of which was covered with a steel plug because of leakage problems) of fused quarts.  At sea level we experience an atmosphere of 14.7 psi.  Seawater depth pressure doubles every 33 feet which means that at 2,200  feet (its deepest dive) the bathysphere must withstand a depth pressure of 3222.06 pounds per square inch.  Imagine an elephant and several comically large anvils standing on your little toe, but that pressure all over the surface of your body.  Squish.
