1. A mustard seed 2 mm

   Despite being tiny, mustard plants can grow taller than a person, a contrast noted in ancient parables.

2. An almond 2.4 cm

   Almonds are seeds of a fruit related to peaches, and raw bitter ones naturally contain traces of cyanide.

3. A Brachiosaurus (length) 22 m

   It held its neck high like a giraffe, possibly needing a heart of enormous power to pump blood up to its brain.

4. The Gateway Arch, St. Louis 195 m

   Its elegant curve is a catenary, the exact shape a hanging chain makes, flipped upside down for strength.

5. Mont Blanc, the Alps 4.8 km

   Its summit is buried under permanent ice so thick that the official height changes slightly with the snow each year.

6. Mount Everest 8.8 km

   Its summit is made of marine limestone, lifted from an ancient seabed, so the top of the world was once underwater.
