By weight · Order from lightest to heaviest.

1. A single drop of water 50 mg

   Pharmacists standardized the 'drop' centuries ago: twenty drops make roughly one milliliter.

2. A giant Pacific octopus 30 kg

   It can squeeze its entire body through any gap larger than its beak — the only hard part it owns.

3. An adult male giraffe 1.2 t

   A giraffe's heart generates about double the blood pressure of most mammals to push blood two meters up its neck to the brain.

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 Empire State Building 331K t

   Built in just 410 days during the Depression, it sat so empty at first that New Yorkers dubbed it the 'Empty State Building'.

6. The supertanker Seawise Giant, fully loaded 650K t
