1. A black peppercorn 4 mm

   Pepper was once so valuable it was used as currency and accepted to pay rent and taxes in medieval Europe.

2. A tournament chess pawn 3.7 cm

   Regulation sets fix the pawn's height relative to the squares so pieces never crowd the board.

3. A tennis ball 6.7 cm

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

4. Mount Fuji, Japan 3.8 km

   Though it looks serene, Fuji is an active volcano that last erupted in 1707, dusting distant Tokyo with ash.

5. Lake Baikal (length) 636 km

   The world's deepest lake holds about a fifth of all the planet's unfrozen fresh water.

6. Norway (length) 1.8K km

   Stretched out, Norway is so long that its northern tip is closer to the North Pole than to its own southern coast.
