Frozen Waterfalls
10 Most Incredible Waterfalls of Ice
BP (before physics) I used to wonder how waterfalls could freeze. But if one looks at the physics, it’s apparent that the motion of water moving in a stream, river or waterfall is small compared to the thermal motion, so this motion really has little effect.
Take a peek at picture #5, showing the frozen outer cylinder, with water still falling inside of it.
Does the Name 'Pavlov' Ring a Bell?
OMG this is TFF.
Have a cat that won’t stay off your counters? I do. I finally got fed up with it enough to do something about it: scare the crap out of him with a motion-detecting blender (while recording the results for my own amusement, of course).
How-I-did-it instructions are included in the link.
Of course, we now have empirical evidence that the number of times you must scare the crap out of a cat in order to modify its behavior is a minimum of 4.
Wouldn’t be science without data.
