By weight · Order from lightest to heaviest.

1. The Hope Diamond 9.1 g

   The famous blue gem glows an eerie red-orange for minutes after exposure to ultraviolet light — a quirk of trace boron inside.

2. An average adult domestic cat 4.2 kg

   Cats purr at frequencies between 25 and 150 Hz — a range some studies suggest can promote bone and tissue healing.

3. The Statue of Liberty 204 t

   Her copper skin is only about as thick as two pennies; the green color is a patina that took roughly 30 years to develop.

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

   Apollo crews rode atop a small warship's worth of kerosene, hydrogen, and oxygen — most of it burned within minutes.

5. A Nimitz-class aircraft carrier 100K t

   A floating city of about 5,000 people, it can sail more than 20 years between refuelings of its nuclear reactors.

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.
