I have to post this, because many people ask me if you can see any fish when crossing the Channel with the Eurostar.
(…well measured pause…)
To everyone’s disappointment, I reveal that the Eurostar train does not actually run under a glass tunnel underwater, but it runs inside an underground tunnel (under-the-ground). Sorry.
For watching fish underwater, I recommend the Sydney Aquarium, the Paris Cineaqua, or an induction to scubadiving in the Read Sea if you dare to get wet.
