1. A single poppy seed 1.3 mm

   It takes roughly 3,000 poppy seeds to make a single gram, which is why they scatter so easily off a bagel.

   Tennis balls are pressurised with gas and slowly go flat, which is why fresh cans hiss when opened.

   Its head holds the largest brain of any animal that has ever lived, weighing about as much as a small person.

   It is struck by lightning several times a year, and repair crews keep spare soapstone to patch the damage.
