1. A FIFA regulation soccer ball 430 g

   World Cup balls are tested in wind tunnels; the 2010 'Jabulani' was so smooth that goalkeepers complained it swerved unpredictably.

2. A standard car tire, without the rim 10 kg

   About a quarter of a tire's mass is not rubber at all — it is steel belts and textile cord hidden inside the carcass.

3. 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.

4. 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.

5. A southern elephant seal bull 3 t

   Bulls can outweigh females several times over — among the most extreme size gaps of any mammal — and dive 1,500 m deep.

6. A fully equipped fire engine 18 t

   Around 2,000 liters of onboard water account for a chunk of the heft — plus ladders, hoses, and hydraulic rescue tools.
