Introduction: How to Keep Your Bottle of Water Cold for HOURS

WARNING:ONLY USE DISPOSABLE WATER BOTTLES! I'M NOT RESPONCIBLE FOR BROKEN NON-DISPOSABLE BOTTLES!!!

Step 1: Step One

First, Get an empty watter bottle. Easy enough.

Step 2: Step Two

Second, fill your watter bottle to the line that I put on my bottle. (You don't have to put the line on)

Step 3: Step Three

Freeze your bottle. I recomend leting it freeze over night for maximum coldness duration. (Pardon my french)

Step 4: (Alternate Step Three)

Freezing the bottle right side up is the easiest way to do it, but if you want a bottle that can stand upright, then I suggest freezing it upsidedown. (If you freeze it upright, the bottom of the bottle will push out, making it almost impossible to set down on a table or any surface for that matter)

Step 5: Step Four

If you froze the bottle upright, then skip ahead to the next step. If you froze it upsidedown, then try to manuver the chunk of ice out of the top so that it can move freely. (I use a screwdriver)

Step 6: Last Step

Just fill the rest of the bottle with water and you're done!

    is this some kind of kid jesus his hands look so tiny lol

    if you freeze it without the cap on, the pressure created from the water expanding should be relieved by the open end, therefore not causing the bottom's rounded expansion you talk about in the next step, allowing it to still be able to sit flat. I've not necessarily tried this, but it should work.

    I am an Eagle Scout, and have seen people I know do this on hikes, I don't for three reasons. One, I usually don't take much water because I don't like the extra weight and don't drink much. Two, the frozen water takes up more space than liquid water, meaning more weight for less water. Third, and I have seen this happen and it is very unfortunate, you may run into unpredicted weather. We took a hike before a three day camp out, and it ended up being 20 degrees colder than predicted, snowing and raining, and the people who froze their water, about 8 out of 10, could not drink it because it didn't unfreeze. If you are hiking, don't do it.

    it still weighs the same just take up a bit more space

    I mean, I only take about 1 bottle of water per 10 miles of hiking.

    i think you're right, and i think it's not so good to drink very cold water . but if you freeze 1 liter of water , you get an ice cube of 1 kilo, but with a volume of 1.2 liter ( i didn't calculate exactly, it's just to explain) . iced water is less dense than flowing water, that's why ice cube ( and iceberg ) float. ( and titanic sink )

    Yeah, that's my point, you can fit more liquid water in you bottle, because when it unfreezes, there's empty space.

    Nice, I do it sideways... it also works good!

    Timheppner has it right: try lying your bottle on its side. You should have a flat-bottomed bottle the next day AND really cold water on tap.
