By weight · Order from lightest to heaviest.

1. A house sparrow 28 g

   House sparrows have followed humans to every continent except Antarctica — one pair even nested deep inside an English coal mine.

2. A FIFA regulation soccer ball 430 g

   World Cup balls are tested in wind tunnels; the 2010 'Jabulani' was so smooth that goalkeepers complained it swerved unpredictably.

3. A Steinway concert grand piano 480 kg

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

4. A Holstein dairy cow 680 kg

   A productive dairy cow gives about 30 liters of milk a day — and burps enough methane to matter in climate accounting.

5. A Saturn V rocket, fully fueled for a Moon launch 3K t

   Apollo crews rode atop a small warship's worth of kerosene, hydrogen, and oxygen — most of it burned within minutes.

6. An Ohio-class nuclear submarine, submerged 18.8K t

   It displaces more than some WWII aircraft carriers and can stay underwater for months, limited mainly by the food supply.
