Quiz — Test Your Understanding

Question 1 of 8
What is the recommended strategy for crash-landing a small airplane on a surfaced submarine?
  • A. Ask the captain to submerge slightly to create a shallow water cushion for the plane's landing gear.
  • B. Have the submarine steer as fast as possible into the wind to create strong headwinds that slow the plane down.
  • C. Fly perpendicular to the submarine's path to avoid crashing into the conning tower.
  • D. Drop the airplane's landing gear into the water just behind the submarine to act as a hydrodynamic brake.
Question 2 of 8
Why does the author suggest using an industrial plastic shredder rather than explosives to open 150,000 bottles of water to fill a swimming pool?
  • A. Explosives would instantly vaporize the water, leaving the pool completely empty.
  • B. The plastic residue from explosives would make the water toxic and unsafe for swimming.
  • C. Explosives cost significantly more to procure than purchasing a brand new industrial shredder.
  • D. Historical government tests showed that beverage bottles can surprisingly survive nuclear explosions intact.
Question 3 of 8
What is the most efficient technique described in the book for digging a massive, mine-sized hole in the ground?
  • A. Using a vacuum excavator to suck up dirt while simultaneously blasting it with high-pressure air or water.
  • B. Detonating underground charges to loosen the bedrock before using a fleet of traditional shovels.
  • C. Removing earth one layer at a time, making each new layer slightly closer to the center like an upside-down layer cake.
  • D. Building a sea wall and allowing localized water pressure to naturally erode the soil over time.
Question 4 of 8
If you successfully build a 900-degree lava moat around your house, what secondary problem must you solve, and how does the book suggest solving it?
  • A. The lava will emit toxic gases; solve this by installing industrial-grade air scrubbers around the perimeter.
  • B. The intense heat will make your house unlivable; solve this by pumping cold water from a nearby body of water through your walls.
  • C. The lava will constantly cool into solid rock; solve this by adding a chemical antifreeze to the molten rock.
  • D. The bright light will blind you during the day; solve this by lowering the temperature to exactly 800 degrees.
Question 5 of 8
How does the book propose generating electricity for an off-grid homestead on Mars?
  • A. By harnessing geothermal energy from Mars's highly active volcanic regions.
  • B. By dragging a tether attached to the moon Phobos through the Martian atmosphere to power a supersonic wind turbine.
  • C. By setting up massive solar panels to capture the uninterrupted, intense sunlight at the equator.
  • D. By extracting and burning the fossil fuels left behind by ancient Martian microbial life.
Question 6 of 8
According to the book, how can a spaceship traveler practically achieve the effect of traveling faster than the speed of light?
  • A. By utilizing the immense gravitational pull of black holes to bend the space-time continuum.
  • B. By accelerating at 10g for short bursts, allowing the ship to break the light-speed barrier without crushing the pilot.
  • C. By continually accelerating at 1g, causing the traveler's subjective time to slow down relative to the outside universe.
  • D. By entering a cryogenic sleep state while the ship's automated systems navigate through theoretical wormholes.
Question 7 of 8
How can a scientist determine if someone is a 'Baby Boomer' (born before the early 1960s) without asking them their age?
  • A. By checking for the presence of microplastics in their bloodstream, which peaked during the 1950s.
  • B. By measuring the calcium density in their bones, which correlates with the introduction of pasteurized milk.
  • C. By examining their DNA for radiation damage caused by the severe depletion of the ozone layer in the 1960s.
  • D. By looking for elevated levels of strontium-90 in their teeth, resulting from mid-century atmospheric nuclear weapons testing.
Question 8 of 8
What unusual strategy does the book highlight for winning a political election, using Pennsylvania as an example?
  • A. Legally changing your name to match a highly recognized and popular political figure to capture confused voters.
  • B. Changing your name to 'None of the Above' so that disgruntled citizens will accidentally vote for you.
  • C. Bribing the officials who design the ballot to ensure your name is placed at the very top.
  • D. Running for multiple state and federal offices simultaneously to guarantee at least one victory.

How To Summary & Overview

This narration is an inviting walk through unusual problem-solving: taking familiar activities and asking, “What if we did this completely differently?” Along the way, it leans on real principles from physics, engineering, and a touch of history to show how creative thinking can still be grounded in evidence.

Some ideas here are intentionally impractical, and the point isn’t to copy them. It’s to practice a mindset: staying open to learning, trying small experiments, and remembering that today’s strange thought can sometimes become tomorrow’s working solution.

Who Should Listen to How To?

  • Listeners who enjoy science-backed “what if” thinking and want a friendly way to stretch their imagination
  • Curious minds who like everyday physics—jumping, sound, throwing, water pressure—explained in a calm, story-like style
  • Anyone who needs a reminder that learning doesn’t end, and that odd ideas can sometimes lead to real breakthroughs
