By weight · Order from lightest to heaviest.

1. A single grain of table salt 60 µg

   Salt crystals are near-perfect cubes because sodium and chloride ions lock into a rigid lattice — about a million grains fit in one cup.

2. A single grain of long-grain rice 25 mg

   Rice feeds more than half the world's population, and farmers cultivate over 100,000 distinct varieties of it.

3. A regulation golf ball 46 g

   The dimples — usually 300 to 500 of them — cut drag so effectively that a smooth ball would fly only about half as far.

4. A kiwi fruit 75 g

   Originally China's 'mihoutao', it was rebranded by New Zealand exporters in 1959 after their flightless national bird.

5. An adult brown rat 350 g

   Rats emit ultrasonic giggles when tickled and come back for more — research that helped earn an Ig Nobel Prize.

6. 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.
