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. 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. A liter of water 1 kg

   The kilogram was originally defined in the 1790s as the mass of exactly this much water — the tie was only fully broken in 2019.

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. A full backyard barbecue propane tank 17 kg

   The familiar grill tank stores propane as a liquid; on a hot summer day the pressure inside can roughly triple.

6. 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.
