Water Bottle as SD tool

[Brian Dale]

Freezing the bottle would make it even harder.

Actually, freezing one of these rugged water bottles won't make them harder.

I think that perhaps she's referring to a comparison with the deformation of the container with flexible bottles made of polycarbonate, polyethylene or polyester terephthalate.

With one of these like your daughter's, you can say, "I carry a SIG(g)."
{Pun intended, hoped for and reached for}

Freezing polycarbonate can break it like freezing a glass jar. I have seen a polycarbonate water bottle ran over by a Bobcat that wasn't broke, although it was so bent the lid wouldn't fit.
I was filling a ploy water bottle half full and freezing it in the evening then filling it up in the morning to have ice cold ice tea at work as we were miles from any electricity. One day I didn't use it and the G/F put it in the freezer for me that evening. The expansion of freezing when full popped the bottom right out by morning. Good way to lose a several dollar water bottle.

Eliph, I was trying to find the care guidelines for polycarb water bottles on nalgene.com and now I can't find it.. but I believe they're safe to freeze so long as they're like 1/3 empty. Sounds like you put yours away full.

Oh, but while I was there I also noted that nalgene is making bottles in different plastics (without bpa if anyone cares) and stainless now too.

Why not have a plastic one for drinking, and then for SD buy a stainless one and fill it to the brim with mercury?

Pax, I did mean full when it broke, freezing when partly full is fine, did it dozens of times with no trouble. IIRC it was a Nalgene bottle.

Why not...for SD buy a stainless one and fill it to the brim with mercury?

At roughly 30 lb. a liter, that'd leave a mark on a BG.

You're obviously kidding (cf. ammonia, above).

At 30lb/l I doubt if you could swing it effectively, but it would absorb recoil well. And at something north of $50/lb I think you'd want to find another material to use.

Freezing the bottle would make it even harder. The only disadvantage is you might need gloves to hold it.

LWG,

Actually, freezing one of these rugged water bottles won't make them harder. Water being an incompressible fluid when filling a bottle completely with no air space is as "hard" as it's going to get. Counterintuitive, but due to the incompressibility property, true.

On the other hand, freezing a standard water bottle might help.

Although LWG could be refering to the solid mass of the frozen fluid as BD mentions, freezing plastic will cause them to be temporarily harder and more brittle until they thaw out. It is the reason why I use paracord to carry bottles that have been frozen instead of the cap's plastic leash.

Cripes. I thought I was the only one who did that. I usually use Lipton Iced Tea mix I buy in cases at SAM's Club. Early on, I filled them up about 80% and froze them without ill effect on the bottle. Problem was they would usually still be frozen by the time I needed them so started filling them up ¼ - ½ full and fill the rest up when I get to work with bottled water. (It was during the time I use to fill them up 80% to the top when I dropped one from about a couple feet high and it broke on the carpet.)

Funny how I never thought about this. In my former life I apparently ruined someone's good time by throwing them out of a club. One of their friends took it upon themselves to throw a full bottle of water at me and it lucked it's way into the bridge of my nose. By that time in my life I had taken more than a few hits, sometimes sucker punches, sometimes with a hidden roll of nickles, once with a set of brass knuckles, but I had never gone completely out. That bottle laid me out cold.

I remember the big glass coke bottles, one plays an important role in family lore. Seems my great-aunt had a husband who liked to drink, and liked to come home after drinking to get alittle punchy. Now this aunt had 3 big brothers, who weren't really known for their physical restraint. Didn't take them long to get tired of seeing sis with bruises so they said they were going to put a stop to it. But sis was proud, and she told them she would take care of it. The next night drunken hubby came home to find his young bride waiting patiently with a full glass coke bottle. Sober and mad beats drunk and sloppy everytime and she calmly beat him into a stroke. Police were called, report was taken. Seems he fell and hit his head on the porch, even the neighbor seen it. To be fair, she nursed him at home for the next 30+ years. No reason to break the marriage vows you know.

One day...

During the time I was filling the Nalgene bottle 80% full, I was running a little late in the morning. To start the thawing process of the frozen iced tea, after taking out the bottle from the freezer, I clipped the bottle (using the paracord loop) into a D-ring carabiner attached to the top handle of my backpack. Being late, I vigorously flung the pack onto my shoulder. The bottle didn't take too kindly to this and proceeded to swing about behind be and smack my right temple. Went to work with a bump on my head.

I found a nice Nalgene bottle back at school. It has handy-dandy finger grooves molded into the sides.

Its almost as if it was designed to be held onto firmly.....

I think it could make for some good whompum if the situation presented itself.
