how to filter water

Since safety matters here, let me search the library for the right way to do this.

Used Retrieve

Based on the field manuals and medical references in your library, here are the proven steps:

Basic steps

  1. Clarification. Let muddy water settle so heavy particles sink. Pour the clearer top through cloth, a coffee filter, or several layers of fabric. This removes sediment but doesn’t make it safe to drink.
  2. Filtration. Pass through sand, gravel, charcoal, or a portable filter to catch smaller particles and most microbes.
  3. Disinfection. Boil for at least 1 minute (3 at altitude), or use chlorine drops, iodine tablets, or UV light.

If you have nothing

If there’s no filter or fabric on hand, dig a shallow hole about a meter from a slow water source and let water seep through the soil into the hole. The soil acts as a coarse pre-filter — but you still have to disinfect afterward, since soil doesn’t kill pathogens.

what about salt water?

Salt water needs distillation, not filtration. Standard portable filters won’t remove salt. Two methods that work:

  • Boil and condense. Boil seawater in a covered pot, collect the steam on a cool lid, and drip the condensate into a clean container. The salt stays behind.
  • Solar still. Dig a pit, place a clean container in the center, cover the pit with clear plastic weighted down in the middle so condensation drips into the container.

Reverse-osmosis filters marked specifically for desalination also work — but they’re a different category of equipment than survival filters.

how about for boiling — how long at altitude?

The CDC and WHO both recommend a minimum of 1 minute at a rolling boil for elevations under 6,500 ft (2,000 m), and 3 minutes above that. Boiling kills bacteria, viruses, and protozoan parasites — including Giardia and Cryptosporidium, which chlorine alone doesn’t reliably handle.

If fuel is scarce, you can pre-treat with chlorine drops or a filter and shorten the boil. Don’t trust appearance — clear water can still carry pathogens.

my friend fell off a ladder and her wrist might be broken

If a wrist is painful, swollen, and won’t bear weight after a fall, treat it as a fracture until you can get her to a clinic. Here’s how to splint it safely:

How to splint a wrist

  1. Don’t straighten it. Splint the wrist in whatever position you find it. Forcing it straight can make things worse.
  2. Pad the area with rolled cloth, foam, or a folded sweatshirt.
  3. Use something rigid as the splint — a rolled magazine, a flat board, two sticks. It should reach from past the elbow to past the fingertips.
  4. Wrap snugly with cloth strips or bandages. Tight enough to immobilize, loose enough that fingers stay pink and warm.
  5. Check circulation every 15 minutes. If fingers go pale, blue, or numb, loosen the wrap.

Then sling the arm against the chest with the hand slightly above the elbow. Get her to a clinic as soon as possible — splinting is a stop-gap, not a treatment.

my furnace pilot light went out and won’t relight

A pilot light that won’t catch is almost always one of three things. Let’s eliminate them in order:

  1. Thermocouple failed or dirty. The most common cause. The thermocouple senses heat from the pilot and tells the gas valve to stay open. If it’s coated in soot or worn out, it won’t keep the valve open after you release the button.
  2. Pilot tube clogged. Dust and lint can block the small opening. A puff of compressed air or a careful poke with a thin wire usually clears it.
  3. Gas supply issue. Check the gas valve handle is parallel to the pipe (open) and that other gas appliances in the house are working.

When relighting, hold the pilot button down for a full 30–60 seconds after the flame catches. The thermocouple needs that long to heat up enough to trigger the gas valve. Release too early and the pilot dies.

If the pilot lights but always goes out the moment you release the button, replace the thermocouple. It’s a $5–15 part and a 15-minute job.

how do I start a sourdough starter from scratch

A sourdough starter is wild yeast and lactobacillus you cultivate from nothing more than flour and water. The whole process takes about a week.

Day by day

  1. Day 1. Mix 50 g whole wheat or rye flour with 50 g water in a clean jar. Stir, cover loosely with a cloth or paper towel — never airtight. Leave at room temperature.
  2. Day 2–3. Discard half. Add another 50 g flour and 50 g water. Stir. You may see a few bubbles starting.
  3. Day 4–7. Discard and feed every 12 hours. By day 5–7 you should see consistent doubling between feedings, a tangy smell, and a network of bubbles. That means the wild yeast has taken hold.

To test if it’s ready: drop a spoonful into a glass of water. If it floats, your starter is strong enough to bake with.

Once established, switch to all-purpose flour and store in the fridge. Feed it once a week — that’s the entire ongoing maintenance.

my tomato plants have brown spots on the leaves and they’re spreading fast

Sounds like blight. There are two kinds — early and late — and they need very different responses. Here’s how to tell which one you have:

Identifying the blight

  • Early blight. Brown spots with concentric rings (a bullseye pattern), starting on the lower, oldest leaves. Spreads slowly. Common, manageable.
  • Late blight. Greasy-looking dark patches on leaves and stems. Whitish fuzz on the underside of leaves in damp weather. Spreads in days. This is the disease that caused the Irish potato famine.

What to do

For early blight: remove affected leaves, mulch around the base of the plants to stop soil splashing onto the leaves, and water at the base instead of from above. Continue harvesting normally.

For late blight: pull up infected plants immediately and destroy them. Do not compost — burn or bag for the trash. The spores travel on wind and can wipe out a whole field within a week.

Both are fungal. Copper-based fungicides slow the spread but won’t cure it. Resistant tomato varieties (Iron Lady, Defiant, Mountain Magic) are your best long-term defense.

FAQ

Common questions.

Does it really work offline?
Yes. After the first download, you can pull the cable out of the wall and never plug it back in. The AI, the library, and the search all live on your laptop.
Is it actually any good?
Wisdoom looks up answers in your library instead of guessing from memory. Every answer shows the exact source it pulled from. If it can’t find a source, it tells you so. No invented facts. No confident nonsense.
Will it run on my laptop?
Almost certainly. Wisdoom runs on any Mac, Windows, or Linux laptop made in roughly the last five years. It tunes itself to your hardware automatically — no setup questions, nothing technical to choose.
Is there a catch?
It’s free and open source. We don’t take payment, sell data, or have any way to lock you in. Anyone can read the source code and verify the claims on this page. The closest thing to a catch: your laptop has to do the work, since there’s no cloud helping it along.
Why “Wisdoom”?
Wisdom + doom. A name that admits what it’s preparing for.

When the lights go out, the library stays on.
