The August stories at the main Flying Circus of Physics site:
(1) Wall-climbing robots. Yes, robots can now climb the external walls of buildings and peer into a room with a camera. And some of them climb by means of quantum mechanics. (2) How snakes slither. (3) Ice spikes that can grow upward from an ice cube. (4) Can you get a vortex in a Miller Lite “vortex bottle,” to drain it quickly? (4) The physics behind a traffic jam. www.flyingcircusofphysics.com New stuff also coming up at Facebook Flying Circus of Physics.
