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 iPhone 15 Pro 187 g

   Its titanium frame is the same alloy grade used in spacecraft and joint implants, trimming heft from earlier steel models.

3. 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.

4. The Antonov An-225 Mriya cargo plane at maximum takeoff weight 640 t

   The heaviest aircraft ever built was destroyed in Ukraine in 2022; 'Mriya' means 'dream' in Ukrainian.

5. The steel arch of the Sydney Harbour Bridge 39K t

   The arch rises and falls up to 18 cm with temperature swings; locals affectionately call the bridge 'the Coathanger'.

6. The Burj Khalifa in Dubai 500K t

   The world's tallest building is tall enough to watch the sunset at the base, ride the elevator up, and watch it set again.
