1. 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.

   Billions of AA cells are produced worldwide every year, making it the planet's most popular battery size.

3. A McDonald's Big Mac 220 g

   The Economist uses Big Mac prices to compare currency values worldwide — the famously tongue-in-cheek 'Big Mac Index'.

4. 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.

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.

   It held the record for largest wingspan of any aircraft until 2019, yet flew exactly once, in 1947 — for about 26 seconds.
