By weight · Order from lightest to heaviest.

1. A compact disc 15 g

   A CD's spiral data track is less than a micrometer wide and would stretch about five kilometers if unwound.

2. 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.

3. An adult Dalmatian 25 kg

   Dalmatian puppies are born completely white; their famous spots only appear after a few weeks.

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 classic yellow American school bus 11 t

   The exact yellow is a legal standard from 1939, chosen because black lettering on it reads fastest in dim morning light.

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.
