By weight · Order from lightest to heaviest.

1. A one-euro coin 7.5 g

   Its two-metal design is not just style — the distinct layers give vending machines an electromagnetic signature to verify.

2. A Thoroughbred racehorse 570 kg

   At full gallop a racehorse's heart pumps roughly 240 liters of blood per minute — ten times its resting rate.

3. 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.

4. A classic yellow American school bus 11 t

   The exact yellow is a legal standard from 1939, chosen because black lettering on it reads fastest in dim morning light.

5. ENIAC, the first general-purpose electronic computer 27 t

   Its 17,468 vacuum tubes filled a huge room in 1945. The phone in your pocket is literally billions of times faster.

6. The London Eye observation wheel 2.1K t

   It was meant to stand for just five years when it opened in 2000; instead it became the UK's most popular paid attraction.
