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. A red kangaroo (standing) 1.5 m

   Kangaroos cannot walk backwards, a trait so iconic it earned them a spot on Australia's coat of arms.

3. A Boeing 737 airliner 34 m

   The 737 is the best-selling jet airliner in history, with one taking off somewhere on Earth every few seconds.

4. 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.

5. The Eiffel Tower 330 m

   It grows up to 15 centimetres taller in summer because the iron expands in the heat.

6. 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.
