By weight · Order from lightest to heaviest.

1. 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.

2. 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.

3. A large chicken egg 57 g

   An eggshell has up to 8,000 microscopic pores, letting the developing chick breathe right through the shell.

4. A stick of butter 113 g

   US butter sticks come in two shapes: the stubby 'Western' stick exists because West Coast dairies bought different molds.

5. A whole Thanksgiving turkey 7.5 kg

   Wild turkeys can fly at up to 90 km/h in short bursts; the broad-breasted domestic birds on holiday tables cannot fly at all.

6. A Space Shuttle orbiter, empty on the runway 78 t

   Returning from orbit, the shuttle was a glider with no engines for a second try — every landing had to work the first time.
