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 giant Pacific octopus 30 kg

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

4. A whole wheel of Parmigiano-Reggiano cheese 38 kg

   Italian banks accept aging Parmesan wheels as loan collateral, storing thousands of them in climate-controlled vaults.

5. 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.

6. A Saturn V rocket, fully fueled for a Moon launch 3K t
