By weight · Order from lightest to heaviest.

1. 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.

2. An official MLB baseball 145 g

   Every game ball is hand-rubbed with mud from a secret spot on a New Jersey riverbank to take off the factory gloss.

3. An average newborn human baby 3.4 kg

   Newborns arrive with about 300 bones; many fuse over the years down to the adult count of 206.

4. A standard car tire, without the rim 10 kg

   About a quarter of a tire's mass is not rubber at all — it is steel belts and textile cord hidden inside the carcass.

5. A Harley-Davidson Road King motorcycle 365 kg

   Harley once tried to trademark its V-twin engine's 'potato-potato' exhaust rumble, then dropped the case in 2000.

6. An adult male African bush elephant 6 t

   The largest land animal walks almost silently — its foot pads expand and absorb sound like cushioned trainers.
