1. A monarch butterfly 500 mg

   Despite weighing less than a paperclip, monarchs migrate up to 4,800 km from Canada to mountain forests in central Mexico.

2. 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.

3. An average adult domestic cat 4.2 kg

   Cats purr at frequencies between 25 and 150 Hz — a range some studies suggest can promote bone and tissue healing.

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

   Its 17,468 vacuum tubes filled a huge room in 1945. The phone in your pocket is literally billions of times faster.

5. A fully loaded 18-wheeler semi-truck 36 t

   Fully loaded, a semi needs about 40% more stopping distance than a car — which is why truckers leave that gap you keep filling.

6. The International Space Station 420 t

   Assembled over 42 flights, it circles Earth 16 times a day at 28,000 km/h, so its crew sees 16 sunrises daily.
