By weight · Order from lightest to heaviest.

1. A regulation golf ball 46 g

   The dimples — usually 300 to 500 of them — cut drag so effectively that a smooth ball would fly only about half as far.

2. A full deck of 52 playing cards 94 g

   Shuffle properly and you have almost certainly created an ordering of the deck no human in history has ever seen before.

3. 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.

4. An adult male western lowland gorilla 160 kg

   Silverbacks are several times stronger than a fit human, yet they eat almost nothing but plants and the occasional termite.

5. 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.

6. A southern elephant seal bull 3 t

   Bulls can outweigh females several times over — among the most extreme size gaps of any mammal — and dive 1,500 m deep.
