1. A house sparrow 28 g

   House sparrows have followed humans to every continent except Antarctica — one pair even nested deep inside an English coal mine.

2. A regulation NBA basketball 620 g

   Each ball is covered in tens of thousands of tiny pebbled bumps, a texture invented so sweaty hands could keep their grip.

3. A large cast-iron skillet 2.5 kg

   Well-seasoned cast iron is essentially a natural nonstick polymer baked onto metal; some American pans have been in daily use since the 1800s.

4. An adult Dalmatian 25 kg

   Dalmatian puppies are born completely white; their famous spots only appear after a few weeks.

5. 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.

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

   The longest ship ever built could not transit the Suez or Panama canals — or even the English Channel — when fully laden.
