Cizo Curiosity Trivia

Question 1

Why does honey found in ancient Egyptian tombs remain edible thousands of years later?

Accepted Answer

Extremely low moisture, high acidity, and bee-produced hydrogen peroxide prevent microbial life

Question 2

What process occurs when bacteria land on honey, causing them to immediately shrivel and die?

Accepted Answer

Osmosis rapidly draws internal moisture out of the bacterial cells

Question 3

Which enzyme do bees secrete into nectar to generate protective gluconic acid and hydrogen peroxide?

Accepted Answer

Glucose oxidase

Question 4

What unique chemical property allows 2,000-year-old Roman concrete structures to survive modern decay?

Accepted Answer

Reactive quicklime clasts that dissolve in rainwater to seal cracks with calcium carbonate

Question 5

What mineral recrystallizes to seal micro-cracks when rainwater seeps into ancient Roman mortar?

Accepted Answer

Calcium carbonate (calcite)

Question 6

What ancient construction technique created the reactive lime clasts inside Roman concrete?

Accepted Answer

Hot mixing quicklime with volcanic ash and water at high temperatures

Question 7

What was the physical object associated with the famous 1947 "computer bug" logged by Grace Hopper’s team?

Accepted Answer

Question 12

How do trees in a dense forest communicate impending pest attacks to neighboring trees?

Accepted Answer

Through subterranean fungal mycelial networks (mycorrhizal networks)

Question 13

What fundamental nutrient exchange occurs between tree roots and mycorrhizal fungi?

Accepted Answer

Fungi supply soil minerals and water in exchange for photosynthesis-derived sugars

Question 14

Why is octopus blood distinctly blue instead of red?

Accepted Answer

It uses copper-based hemocyanin to bind and transport oxygen

Question 15

Why do octopuses often prefer crawling along the seabed rather than swimming?

Accepted Answer

Question 16

How is circulatory labor divided among the three hearts of an octopus?

Accepted Answer

Two branchial hearts pump blood through the gills, while one systemic heart circulates blood to the body

Question 17

How has Oxford University’s Clarendon dry pile battery kept a bell ringing continuously since 1840?

Accepted Answer

It runs on an ultra-low nano-ampere electrostatic charge between bells

Question 18

Approximately how many oscillations has the Oxford Electric Bell completed since it was installed?

Accepted Answer

Over 10 billion cycles

Question 19

What physical force drives the motion of the 4mm clapper between the two bells?

Accepted Answer

Electrostatic attraction and repulsion

Question 20
