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. An adult male white rhinoceros 2.3 t

   The 'white' is likely a mistranslation of the Dutch 'wijd', meaning wide — describing its broad, lawn-mowing mouth.

3. An adult male Asian elephant 4 t

   You can tell it from its African cousin by the much smaller ears and the twin domes on its forehead.

4. The London Eye observation wheel 2.1K t

   It was meant to stand for just five years when it opened in 2000; instead it became the UK's most popular paid attraction.

5. The Motherland Calls statue in Volgograd, Russia 8K t

   Twice the height of the Statue of Liberty, sword included, she is not anchored to her base — held in place by gravity alone.

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.
