1. A single sesame seed 3 mg

   Sesame is one of humanity's oldest oil crops, domesticated in South Asia more than 3,000 years ago.

   Heavier than a grain of rice — staples are solid steel wire, and a standard strip glues 210 of them together.

3. A FIFA regulation soccer ball 430 g

   World Cup balls are tested in wind tunnels; the 2010 'Jabulani' was so smooth that goalkeepers complained it swerved unpredictably.

4. A large cast-iron skillet 2.5 kg

   Well-seasoned cast iron is essentially a natural nonstick polymer baked onto metal; some American pans have been in daily use since the 1800s.

5. A full backyard barbecue propane tank 17 kg

   The familiar grill tank stores propane as a liquid; on a hot summer day the pressure inside can roughly triple.

6. A Harley-Davidson Road King motorcycle 365 kg

   Harley once tried to trademark its V-twin engine's 'potato-potato' exhaust rumble, then dropped the case in 2000.
