[PSUBS-MAILIST] syntactic foam.

[hank pronk via Personal_Submersibles]

I have an idea, but not sure if it will work.  My idea is to fill a neutrally buoyant container with macro and micro spheres.  After the container is as full as possible, then fill with an environmentally friendly oil.  This would be more buoyant than using a resin and less complicated and cheaper.  My concern is, how well will the spheres stand up against breaking from being in contact with the other spheres and the container.   Are these spheres delicate?  Hank
