Not sure if this avenue has been explored before, but this would put an interesting spin on ice slugs:

Cool stuff! Just mill some down on a lathe and there you go! You could make some nice and durable custom projectiles.

Funny, I just saw a program on the History Channel not too long ago about pykrete. It never occured to me that it would make for a great projectile. Great thinking, FMJ! I wonder if I could make a similar substance from the huge bin of PVC shavings and chips in my basement... I don't have much sawdust, but I've got tons of PVC trash [:p]

I think the idea is to have something water soluble [:p]

According to the wiki article, "Pykrete can be easily formed using water and common pulp, such as toilet paper or paper towels. Basically anything you can mold with this wet pulp will freeze and be extremely hard and cold."

Yeah, from what I understand the strength is to a degree from the lattice that the wood pulp or similarly porous material can sustain, but I wonder if any similarly sized chunks of material could add <i>some</i> reinforcement, like rebar in concrete? Nothing serious, just a passing thought.:)

I doubt it would make much of a difference using non-porous materials, simply because frozed water does not have the adhesive properties of dried concrete...

I don't get the part about the aircraft carrier?

The cost of keeping your freezer cold should be considered.

My thoughts and ballistics tests can probably be summed up best by simply refering you to the <a href="http://www.spudfiles.com/spud_wiki/index.php?title=Pycrete">spudwiki artical</a> I wrote about the substance.
