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 one-euro coin 7.5 g

   Its two-metal design is not just style — the distinct layers give vending machines an electromagnetic signature to verify.

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 regulation NBA basketball 620 g

   Each ball is covered in tens of thousands of tiny pebbled bumps, a texture invented so sweaty hands could keep their grip.

5. A Thoroughbred racehorse 570 kg

   At full gallop a racehorse's heart pumps roughly 240 liters of blood per minute — ten times its resting rate.

6. A Saturn V rocket, fully fueled for a Moon launch 3K t

   Apollo crews rode atop a small warship's worth of kerosene, hydrogen, and oxygen — most of it burned within minutes.
