By size · Order from shortest to longest.

1. A common garden ant 5 mm

   Ants can lift objects many times their own weight thanks to their tiny size and the physics of scale.

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 giant sequoia (tallest) 89 m

   These trees can live over 3,000 years, and their thick bark resists fire that clears competing plants away.

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. The CN Tower, Toronto 553 m

   Its glass floor can hold the weight of dozens of moose, yet many visitors still cannot bear to step on it.

6. The Brooklyn Bridge (total length) 1.8 km

   When it opened in 1883, a stampede fearing collapse killed twelve people; a circus later marched elephants across to prove its strength.
