By weight · Order from lightest to heaviest.

1. An adult male wild boar 90 kg

   Wild boars are thriving so well they have spread or been introduced to every continent except Antarctica.

2. An adult male African lion 190 kg

   A lion's roar can be heard up to 8 km away, thanks to uniquely flat, square-shaped vocal folds.

3. 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.

4. A fully loaded 18-wheeler semi-truck 36 t

   Fully loaded, a semi needs about 40% more stopping distance than a car — which is why truckers leave that gap you keep filling.

5. A SpaceX Falcon 9 rocket, fully fueled on the launch pad 549 t

   More than 95% of that is propellant; the reusable first-stage booster lands weighing almost nothing by comparison.

6. The Golden Gate Bridge 805K t

   Its two main cables contain enough wire to circle the Earth three times, and painting crews never actually finish — they cycle forever.
