By weight · Order from lightest to heaviest.

1. A large chicken egg 57 g

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

2. A giant Pacific octopus 30 kg

   It can squeeze its entire body through any gap larger than its beak — the only hard part it owns.

3. An average adult human, averaged across the whole world 62 kg

   Researchers computed this from global census data; North America's average is about 20 kg heavier than Asia's.

4. A full-size kitchen refrigerator 135 kg

   Refrigeration changed cuisine more than almost any invention; Einstein even co-patented a fridge with no moving parts in 1930.

5. An adult blue whale 140 t

   The largest animal ever known has a heart the size of a small car, and its calves gain roughly 90 kg per day on milk alone.

6. The Great Pyramid of Giza 5.8M t

   Roughly 2.3 million stone blocks were stacked over about 20 years — averaging a block placed every few minutes of every workday.
