SortStack #853 — 2028-10-09

By size · Order from shortest to longest.

1. A single E. coli bacterium 2 µm

   About 2 micrometres long, E. coli divides every 20 minutes, so one cell can become billions inside a single day.

2. A grain of table salt 0.5 mm

   Each crystal is a near-perfect cube because salt's atoms stack in a rigid cubic lattice.

3. An orca (killer whale) 8 m

   Orcas have distinct dialects passed down through families, essentially regional accents that differ between pods.

4. The Eiffel Tower 330 m

   It grows up to 15 centimetres taller in summer because the iron expands in the heat.

5. The Channel Tunnel 50.5 km

   Trains run through three parallel tubes beneath the seabed, with a smaller service tunnel between them for safety.

6. The River Thames (length) 346 km

   It was once so polluted that 1858's 'Great Stink' forced Parliament to finally build London's sewers.
