By weight · Order from lightest to heaviest.

1. A modern US penny 2.5 g

   Pennies have been mostly zinc since 1982 — only the thin outer coating is actually copper.

2. A large chicken egg 57 g

   An eggshell has up to 8,000 microscopic pores, letting the developing chick breathe right through the shell.

3. The FIFA World Cup Trophy 6.2 kg

   Winners only keep a gold-plated replica; the 18-karat original stays with FIFA and gets each champion engraved on its base.

4. The Liberty Bell 943 kg

   Its famous crack was widened on purpose — an 1846 repair meant to stop the fracture instead ruined the bell's tone for good.

5. A Tesla Model 3 1.8 t

   Around a quarter of the car's entire mass is its battery pack, mounted in the floor for a racing-car center of gravity.

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.
