1. An adult house mouse 19 g

   Male mice sing ultrasonic courtship songs too high-pitched for humans to hear, with repeated phrases like birdsong.

2. A full deck of 52 playing cards 94 g

   Shuffle properly and you have almost certainly created an ordering of the deck no human in history has ever seen before.

   Researchers computed this from global census data; North America's average is about 20 kg heavier than Asia's.

4. An adult male African lion 190 kg

   A lion's roar can be heard up to 8 km away, thanks to uniquely flat, square-shaped vocal folds.

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 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.
