Waves in a Large Free Sphere of Water

Check out this interesting video of a large sphere of water in microgravity.  Also shown is a air bubble inserted inside the sphere, and then small water droplets bouncing around inside of that air bubble!  Both of these segments show how strongly the surface tension of a liquid governs it’s behavior.  The last segment shows a very hydrophilic antacid tables ‘sucked’ in by the large water sphere and immediately dissolving.

Cold War test, fighter jet slams into concrete wall.

9/11 conspiracy theorists like to point to the wall of the pentagon and freak out over how ‘little’ damage there is and that there was little debris.  But aircraft are mostly air, and what’s not air is almost entirely very thin aluminum.  The only thing of significant strength and density is the engine, which is in fact what punched a whole through the wall of the pentagon.  Look at this Cold War era video, meant to test the effects of a jet slamming into a concrete wall of a nuclear reactor (clearly suicide attacks were on the consciousness of some people) the Jet virtually disintegrates. Debris?  What Debris?
