"If'n I'm gonna fall, someone is gonna' watch."
I discovered this trick when I was about 15 and camping on the south shore of Lake Superior in the early spring. We were in a tent on the beach and it got cold -- darned cold. My sleeping bag was lined with flannel on the inside and a thin canvas on the outside -- I shudder to think I spent my outdoor youth in suc a contraption.
We had a big beach fire that continued to burn and smolder after we turned in. The fire wa ringed with some small boulders. The boulders were nice and smooth. When I got chilled I got up and sat next to the fire and stoked it to warm up. I realized that the boulders ringing the fire were warm, and some were not too warm to the touch. So, when I headed back to bed, I brought a toasty boulder with me and tossed in into the foot of my bag -- it kept me nice and warm for hours. When the warmth dissipated, I just went out and stoked the fire again and grabbed another rock.
I assume a rock not too hot to touch would not melt nylon? It didn't harm my flannel lining other than to introduce a bit of dirt and sand. I assume water can get much hotter than the temperature of the rocks I was selecting, so wrapping the bottle in cloth to avoid burns makes sense. I suppose one could place a few rocks into a flannel pillowcase to allow some hotter rocks to be used and to avoid tacking dirt into one's bed. In a hammock one would have to tie the bottle or pillowcase to the foot end of the hammock to prevent it from migrating toward the center while sleeping?
I'd just lay it on my belly and snuggle with it!
When picking rocks to put by the fire, don't get them from the river or out of the water. If there's any water trapped in a crack or a pocket in the rock, it can make the rock explode when the water heats and expands.

IMPOSSIBLE JUST TAKES LONGER
i use one of these VS a hot water bottle..... 12-16 hours of heat on just 1.0 oz of fuel.
since it doesnt really burn (it catalyzes the fuel) i feel very safe using it in the foot box of my sleeping bag to keep my feet toasty all night and in my shirt pocket the rest of the time im not in the bag.... happiness is a warm boob on a cold day

New to the forums and just finding this topic. I've never used a hot water bottle, but generally use a found rock. A little smaller half the size of a soccer ball, I suppose I always think of it as cannon ball size for some reason...throw it in the fire for about an hour and a half. Fish it out of the fire and either roll it into a small towel of some such. I have a little canvas pouch that I roll it into. It will stay warm all night. You can pick up a new rock where ever you are, unless of course you get attached to your rock and want to carry it around
I have used this in a tent, and on plain ground when 'minimalist' camping. Put some medium (fist sized) rocks or stones in your campfire (NEVER use wet stones ...they could explode from the steam build-up!).
Dig a shallow line trench right under where you will be sleeping, and move the stones (using tongs from sticks) in the trench, and even being above it, put a small layer of dirt or sand over them. Disperses the heat, and keeps them from being cooled-off too quickly by wind.
The hot stones will send heat upward for hours. Warms yer bottom!
I've heard of this trick many times but have never tried it. Really like the sock idea. I have a couple worn and stretched out wool socks that would be perfect for this. Thanks for the reminder...
I've been using a rubber water bottle that I bought from Walmart. It's the kind that comes with all kinds of hoses and nozzles and such so it can be used as a douche bag or an enema. No need for all those fancy accessories, so I just kept the water bottle. I like it because it's flat when empty and it seals very well and doesn't leak. I fill it with hot water and then stuff it down into the toe area of my sleeping bag. Very nice.
On a side-zip, or top-loading, hammock you just lean out. Seriously, it takes a bit of balance control, but it avoids getting all the way out from under your warm quilts. One must be very diligent about where one keeps his boots (or goats), but that's the only real obstacle. Again, practice is required.
