  Hi the other Rick. Lol. 

  Expensive huh?  How expensive is expensive? 

  Can one buy the glass balls and make up their own epoxy/ball mix? 

  Anyone tried their own mix that way? 

  Bill.

      Hi Rick.

      Ahhhh, I see. So these tiny little glass balls are all mixed up in the epoxy and this takes the shape of

      whatever it's poured into and becomes uncompressable ballast. Cool! Where can you get this syntactic foam?

      Thanks, Bill.
