1. A single sesame seed 3 mg

   Sesame is one of humanity's oldest oil crops, domesticated in South Asia more than 3,000 years ago.

2. An average adult domestic cat 4.2 kg

   Cats purr at frequencies between 25 and 150 Hz — a range some studies suggest can promote bone and tissue healing.

3. A front-loading washing machine 76 kg

   Much of the heft is a deliberate concrete counterweight — without it, the spin cycle would walk the machine across your floor.

   Its famous crack was widened on purpose — an 1846 repair meant to stop the fracture instead ruined the bell's tone for good.

5. A Tesla Model 3 1.8 t

   Around a quarter of the car's entire mass is its battery pack, mounted in the floor for a racing-car center of gravity.

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'.
