Ok, think Ice.
Now think about ice that takes ages to melt.
Now think about ice that doesn't break no matter what you shoot it at.

You have just imagined pycrete!

here and here

steps:

1) take paper and rip it up, then put it in a blender with water to make a pulp. the ideal ratio of paper to water should be about 15:85.

2) take the pulp and stuff it down a section of the pipe you used as your barrel and freeze it over night, or maybe longer, this stuff takes as long to freeze as to melt.

I shot it many times and no damage was done to it by 1" sheets of plywood

edit: title fixed

I must investigate this....

Doesn't the real pycrete use saw dust instead of paper?

yeah i'm pretty sure it does. i saw some where during WWII they tried to make a battle ship out of it.

Even so, shredded paper is pretty much the same as saw dust isnt it? Also, it's spelled Pykrete. How long does it take to freeze?

Using pykrete as an ammo has been discussed before. We've even discussed having pieces of metal dispersed all throughout it to increase its density. (I forget which member it was who came up with that idea though)

Pykrete is actualy pretty well known. Although I still have to experiment with it, it does sound promising, and yes, the Germans did hypothesize a ship made out of it during WWII. They also imagined a tank toated in the air by an airplane. That's kind of ghetto...

I believe the Brit's are the ones that considered, and almost started construction on, a pykrete aircraft carrier.

The Wiki on Pykrete is pretty good.

Yep, we've discussed Pykrete here a few times before:

I've actually tried forming some slugs out of it - it expands quite a bit in freezing which makes it a slight pain in the arse to mold, but they make awesome projectiles if you have some patience.

Wouldn't it eventually melt?
Or would it beused in col temperatures?

Yeah sorry. The English did invent pykrete, and did propose the idea of an aircraft carrier made of it. Here's a really cool link about the carrier... http://www.metacafe.com/watch/235665/2_ ... er_in_ww2/

EDIT: Whoops. I just noticed Pete Zaria's post which has the same link. My bad!

"no matter what you shoot it at"
Yeah, whatever.

It fragments quite readily if you shoot it at a rock, as I relate in the spudwiki article on the stuff.
