By weight · Order from lightest to heaviest.

1. A compact disc 15 g

   A CD's spiral data track is less than a micrometer wide and would stretch about five kilometers if unwound.

2. A stick of butter 113 g

   US butter sticks come in two shapes: the stubby 'Western' stick exists because West Coast dairies bought different molds.

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. The FIFA World Cup Trophy 6.2 kg

   Winners only keep a gold-plated replica; the 18-karat original stays with FIFA and gets each champion engraved on its base.

5. An adult male Asian elephant 4 t

   You can tell it from its African cousin by the much smaller ears and the twin domes on its forehead.

6. A SpaceX Falcon 9 rocket, fully fueled on the launch pad 549 t

   More than 95% of that is propellant; the reusable first-stage booster lands weighing almost nothing by comparison.
