-Caveat Lector-
I once did some research that turned me on to a product
called starbright or something along those lines...it
expands exponentially when wet...it is used to crumble bank
vaults in buildings banks have dehabitated...a restaurant
interest I was involved with bought a bank building but the
vault was a real problem....they drilled the concrete in
numerous places with masonry bits, injected wet starbright,
and in the morning the vault was in pieces on the
floor...nice to know about these things...a drum or two of
that in the right crevice of the oceans floor would wreak
havoc I am sure. Easy as pie.
