Best way to light a tent I assume by "torch" you mean what we Americans would call a "flashlight." Our torches would be quite dangerous in a tent. |

How to tell if water is likely to have cryptosporidium? I'm not sure enough to post as an answer, but I suspect the only way is if there is a warning about it, usually from some government agency. |

Which will keep my food colder longer, draining the melted ice water, or leaving it in the cooler? At meltB, if (as you are saying) there is less heat energy in cooler B, the ice will NOT be all melted unless it was already fully melted in cooler A. It takes the exact same amount of energy to melt the exact same amount of ice, regardless of conditions. |

If k were constant, the temperature would be directly proportional to your (still incorrect) graphs. However, the average k of the drained cooler is dropping, so the temperature is increasing even faster. (Though, as I said, not until the ice is all melted.) |

Oh, and I should mention, the temperature doesn't increase linearly, they will both be at a constant 32 until all ice is melted (except small jumps for draining the ice in the appropriate cooler), after which the temperature difference will decay exponentially (with the water-filled cooler rising much more slowly). |

Which will keep my food colder longer, draining the melted ice water, or leaving it in the cooler? "Both leak heat at the same rate," and "at meltB there is less heat energy in cooler B than in cooler A," but "B's ice will be completely melted before A's ice is." Those can't all be true. In fact, the amount of ice in the cooler depends entirely on how much heat energy there is in the cooler, so by acknowledging that there will be more heat energy in the drained cooler, you are actually saying that the ice in it will melt faster. |

Which will keep my food colder longer, draining the melted ice water, or leaving it in the cooler? Also, the fact that the water is still at freezing will inhibit bacteria from growing. |

Water with ice in it will remain at 32F until all the ice is melted (assuming it's not being heated so rapidly convection can't even things out - and if that's the case, you have bigger problems with your cooler). |

Is the “Rule of 3” proven for food? Interesting. Last I heard was two for each of those. |

Will bug repellent repel deer? If you can smell it, you can be sure the game can. What you really need is a repellent they won't mind. |

How can I make/improvise a rope on a trip? @jay you're right, I've also added location. |

How can I make/improvise a rope on a trip? @berry120 certainly not climbing, though perhaps a separate question could be asked about getting down when you drop a rope. I've clarified. |

Are there any cheap 1:25K electronic maps for the UK or Europe? @Shog9 It's not too localized; if the problem is the shopping aspect, it should be reopened and re-closed as off-topic. |

What are some toilet paper alternatives you could use in the woods? I don't know about the snowball, that's going to be awfully cold. |
