By weight · Order from lightest to heaviest.

1. A black garden ant worker 1.5 mg

   Ants can carry 10 to 50 times their own body weight — the square-cube law makes tiny bodies absurdly strong for their size.

2. The Hope Diamond 9.1 g

   The famous blue gem glows an eerie red-orange for minutes after exposure to ultraviolet light — a quirk of trace boron inside.

3. An official MLB baseball 145 g

   Every game ball is hand-rubbed with mud from a secret spot on a New Jersey riverbank to take off the factory gloss.

4. A standard Good Delivery gold bar, the kind in bank vaults 12.4 kg

   Smaller than a brick yet heavier than most pet dogs — gold is so dense this bar would fit in a shoebox with room to spare.

5. An adult Tyrannosaurus rex 8.5 t

   'Sue', the most complete T. rex ever found, sold at auction in 1997 for $8.4 million and now has its own social media accounts.

6. The steel arch of the Sydney Harbour Bridge 39K t

   The arch rises and falls up to 18 cm with temperature swings; locals affectionately call the bridge 'the Coathanger'.
