1. A AA alkaline battery 24 g

   Billions of AA cells are produced worldwide every year, making it the planet's most popular battery size.

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

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.

   It can squeeze its entire body through any gap larger than its beak — the only hard part it owns.

5. An adult Tyrannosaurus rex 8.5 t

   'Sue', the most complete T. rex ever found, sold at auction in 1997 for $8.4 million and now has its own social media accounts.

6. 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.
