Alien Invasion: 60 days on the 60th floor

At 9:40 on a Thursday night you're in a window washer's cradle 60 floors up when a light comes out of the clouds and every window in the city goes dark. One water tank, rules written in chalk, and lamps that take anything that glows.

The rules in chalk

1No light after darkPale green lamps sweep the streets, and anything that glows gets taken. A light 700 feet up clears the horizon for about 32 miles.
2Stay behind glassWindow glass reflects the long wave infrared a heat camera sees, so it shows a mirror, not you.
3No radioBearings from two places can pin a transmitter on a map.
4Nothing that repeatsSound moves through steel about 17 times faster than through air, and a tower is a steel frame.

Why the rules work

Stealth runs on physics

Every rule on that board is real science: how a heat camera sees glass, how radio direction finding works, how water hammer rings a building, and how plain bleach makes tank water safe to drink.

What is real in this story (15 sourced facts)

Window glass reflects the long wave infrared a heat camera sees, so it shows a mirror image, not what's behind the glass. Firehouse ↗
Bearings from two or more places can locate a radio transmitter (radio direction finding). Wikipedia ↗
Shut a valve fast and the water slams to a stop, sending a pressure spike through the pipe (water hammer). Close valves slowly. Practical Engineering ↗
A closed fridge keeps food cold about 4 hours without power. Toss food that sat at 40 degrees or higher for 2 hours or more. Ready.gov ↗
Store at least a gallon of water per person per day; in very hot weather the need can double. Ready.gov ↗
Heat exhaustion: heavy sweating, pale clammy skin, dizziness. Move somewhere cooler, apply cool wet cloths, offer sips of water. Weather.gov ↗
Never use a generator inside, even with doors and windows open. It makes carbon monoxide. CDC ↗
Sound moves through steel at about 5,940 meters a second, about 17 times faster than through air. Engineering ToolBox ↗
To stop bleeding, press firmly and don't peek. If blood soaks through, leave the cloth and add another on top. MedlinePlus ↗
Watch a cut for warmth, redness, swelling, pus or fever. MedlinePlus ↗
Full dark adaptation can take up to 30 minutes, and dim red light won't impair night vision. FAA ↗
8 drops of 6 percent unscented bleach per gallon of clear water, wait 30 minutes. No faint chlorine smell? Repeat and wait 15 more. EPA ↗
One inch of rain on 1,000 square feet of roof is about 623 gallons. USGS ↗
Seconds from flash to thunder divided by 5 gives miles. If you can hear thunder, you're within striking distance. Weather.gov ↗
Knots weaken rope: a bowline keeps about 67 to 75 percent of its strength, a square knot about 43 to 47 percent. Practical Sailor ↗

Also real: Rolled oats are steamed before they're flaked, a phone checks in with the network even when you don't touch it, SOS is three short, three long, three short, and a light 700 feet up clears the horizon for about 32 miles.

This is a fictional animated story. The aliens are made up; the survival science is real.

Zombie Outbreak: Survive 100 Days Trapped In A Hospital

You're the night engineer at a 180 bed hospital when the outbreak reaches the emergency department just before midnight. By morning the grid is gone, the dead are on the wards above you, and you have one diesel generator, one lit floor and a fuel gauge you can't fully trust.

The generator is dead, the yard is empty for the first time, and the fire panel reports a pull station on the sealed fourth floor. You and Noor need another 100 days with no grid, very little diesel and insulin that only lasts 28 days without cold.

For 80 days the alarm at station two went off nine minutes after every engine run, and you logged it as a fault. It was a hand. Getting night nurse Ravi out of sealed 4 East means your first real contact with the dead in 217 days, while winter waxes up the diesel.
