By weight · Order from lightest to heaviest.

1. A modern US penny 2.5 g

   Pennies have been mostly zinc since 1982 — only the thin outer coating is actually copper.

2. A classic yellow American school bus 11 t

   The exact yellow is a legal standard from 1939, chosen because black lettering on it reads fastest in dim morning light.

3. ENIAC, the first general-purpose electronic computer 27 t

   Its 17,468 vacuum tubes filled a huge room in 1945. The phone in your pocket is literally billions of times faster.

4. 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.

5. The Eiffel Tower 10.1K t

   The iron grows in summer: heat expands the sun-facing side, leaning the top away from the sun and adding around 15 cm of height.

6. An Ohio-class nuclear submarine, submerged 18.8K t

   It displaces more than some WWII aircraft carriers and can stay underwater for months, limited mainly by the food supply.
