Got to love the difference between a decent piece of journalism and the version of that same report i read in 'The Sun' earlier (notorious imho for getting some very simple details wrong and exagerating things!)
Headline: Mall Shoppers Flee 400 Sharks...Terror as 10m-gallon aquarium cracks open
Apparently 'water gushed through a gap in the 30 inch thick acrylic glass'
10m-gallon? acrylic glass? (is it made from acrylic or glass?!?!?!) i think they need to check their details and interview more than just the one person that reported it as 'exploding'
