SortStack #2016 — 2031-12-16

By weight · Order from lightest to heaviest.

1. A single kernel of corn 300 mg

   Each kernel is botanically a complete fruit, and a typical ear carries an even number of rows — most often sixteen.

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. 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.

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. An adult male African lion 190 kg

   A lion's roar can be heard up to 8 km away, thanks to uniquely flat, square-shaped vocal folds.

6. The London Eye observation wheel 2.1K t

   It was meant to stand for just five years when it opened in 2000; instead it became the UK's most popular paid attraction.
