By weight · Order from lightest to heaviest.

1. An unfed female mosquito 2.5 mg

   After a full blood meal a mosquito can double or even triple her weight — and still fly away with the loot.

2. A brilliant-cut one-carat diamond 200 mg

   The carat unit comes from carob seeds, which ancient gem traders used as counterweights on their balance scales.

3. A AAA alkaline battery 11.5 g

   Despite the tiny package, a fresh AAA stores enough energy to hoist an adult human several meters into the air.

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. Big Ben, the Great Bell of Westminster 13.8 t

   Big Ben is the bell, not the tower — and it cracked within months of entering service in 1859; the odd tone is the crack.

6. The London Eye observation wheel 2.1K t

   It was meant to stand for just five years when it opened in 2000; instead it became the UK's most popular paid attraction.
