By weight · Order from lightest to heaviest.

1. An Etruscan shrew, the world's smallest mammal by mass 1.8 g

   Its heart beats up to 1,500 times a minute, and it must eat about twice its body weight in insects every single day.

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. A round loaf of sourdough bread 800 g

   Some sourdough starters are family heirlooms over 150 years old, kept alive by daily feedings of flour and water.

4. An adult male African bush elephant 6 t

   The largest land animal walks almost silently — its foot pads expand and absorb sound like cushioned trainers.

5. A fully equipped fire engine 18 t

   Around 2,000 liters of onboard water account for a chunk of the heft — plus ladders, hoses, and hydraulic rescue tools.

6. The CN Tower in Toronto 117.9K t

   It held the title of world's tallest free-standing structure for 32 years, and its glass floor was the world's first.
