By weight · Order from lightest to heaviest.

1. A whole pineapple 1.2 kg

   Pineapples take nearly two years to grow, and each plant produces just one fruit at a time.

2. A large cast-iron skillet 2.5 kg

   Well-seasoned cast iron is essentially a natural nonstick polymer baked onto metal; some American pans have been in daily use since the 1800s.

3. A Holstein dairy cow 680 kg

   A productive dairy cow gives about 30 liters of milk a day — and burps enough methane to matter in climate accounting.

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. 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.
