    The falling water bottle was an awesome way to demonstrate the equivalence principle.
    Brian Greene mentions very quickly that the curvature in time as well as space is important and doesn't go into it more, but he means something like this: the rubber sheet represents spatial curvature and you can slice spacetime so you have many copies of the rubber sheet stacked together. Moving forward through time forces you to move upward through the stack, but the *true* time direction you experience gets pulled slightly inward by gravity, so your overall motion arises as the combination of both space AND time bending toward the sun.

      Holy shit, thank you for that comment!
      It made me think deeper into the problem, and I think I finally got it!
      So basically, it's like time is just another spacial dimension, in which we are moving with constant velocity(which we preceive as time passing by) at all times, and the curvature, which mass produces, extends into the future(which is basically just a direction if we consider time as a spacial dimension), and the fact that objects with mass get drawn into that curvature is due to that constant movement in time!

      It's even stronger than that. The overwhelming majority of the acceleration we experience towards the earth - and everything experiences towards everything else - comes from the curvature in time specifically, not of space. Spatial curvature contributes to more exotic effects like lensing and black hole dynamics.

      @@jmcsquared18 exactly I was just going to explain that. For the most part, gravity is just matter bending space so that relative to spacetime curvature, you're actually not moving through space at all but only through time when you and another object of mass accelerate towards one another.

That's because if the cap had been closed too tightly, then there wouldn't be any atmosperic pressure acting on the water due to the air on top of it. In other words, the water would not have "fallen" out of the holes. By adjusting the tap, he is making sure that there is pressure acting on the water, almost "squeezing" it so that the water would come out of the holes.
