October stories at the FCP main site

October stories at the main FCP site: (1) At night, an sand scorpion uses waves in the sand to precisely locate a beetle (for lunch). (2) The canal effect, in which the passage of a ship on a waterway can drain an adjoining canal and then rapidly refill it (to the dismay of the fish). (3) If it weren’t for mass dampers, people living or working in tall buildings would have motion sickness every time the wind would blow. (4) Pub trick: grab three table knives and then place three pub glasses at the corners of an isosceles triangle, separated by a distance greater than a knife length. Can you balance the knives on the glasses and then a wine bottle on top of the knives?
