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.

   It is about 2% of your body weight yet burns roughly 20% of your energy — mostly just keeping billions of neurons ready to fire.

3. An adult male wild boar 90 kg

   Wild boars are thriving so well they have spread or been introduced to every continent except Antarctica.

4. ENIAC, the first general-purpose electronic computer 27 t

5. An M1 Abrams main battle tank 62 t

   Despite the bulk it tops 65 km/h, powered by a jet-style gas turbine engine that can run on almost any fuel.

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