- A sheet of A4 printer paper 5 g
A-series paper is metric by design: every size is exactly half the one above it, all sharing the same elegant proportions.
- A full deck of 52 playing cards 94 g
Shuffle properly and you have almost certainly created an ordering of the deck no human in history has ever seen before.
- A round loaf of sourdough bread 800 g
Some sourdough starters are family heirlooms over 150 years old, kept alive by daily feedings of flour and water.
- An adult male giraffe 1.2 t
A giraffe's heart generates about double the blood pressure of most mammals to push blood two meters up its neck to the brain.

Hippos cannot actually swim — they sink and gallop along the riverbed, surfacing to breathe every few minutes.
- A Boeing 777-300ER airliner at maximum takeoff weight 351.5 t
Each of its GE90 engines is so wide that a Boeing 737 fuselage could very nearly fit inside the cowling.
