By weight · Order from lightest to heaviest.

1. A single office staple 33 mg

   Heavier than a grain of rice — staples are solid steel wire, and a standard strip glues 210 of them together.

2. A one-euro coin 7.5 g

   Its two-metal design is not just style — the distinct layers give vending machines an electromagnetic signature to verify.

3. 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.

4. A Steinway concert grand piano 480 kg

   Each Steinway Model D takes about a year to build and contains over 12,000 individual parts.

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. 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.
