For a little Friday fun, enjoy this timelapse of magnetic putty consuming magnets. Really this is a bit of slow-motion magnetohydrodynamics. The magnet’s field exerts a force on the iron-containing putty, which, because it is a fluid, cannot resist deformation under a force. As a result, the putty will flow around the magnet, eventually coming to a stop once it reaches equilibrium, with its...

shiftymctwizz asked: So I just read your post about vortices, and now I'm wondering if we could build structures similar to the Corryvreckan and put turbines in them for energy production? Would it be any more efficient than hydroelectric dams? Are you the right person to ask?

corroding-touch asked: So, further to the wave question, how about pressure? How does the pressure in a fixed spot beneath a wave vary, and how does this change with depth?

captainandry asks: What would happen to a fish or swimmer in a standing wave? First of all, check out the video that inspired this question, which shows a standing water wave created in a wave tank. Before we tackle the standing wave, it’s helpful to know what motion exists in a typical water wave. For deep water waves, the motion of a particle as the waves pass is circular, with a...
