      Because of physics

      @@kasim7929 forgot the solution given last time, but I bet top ampoule is heavy, bottom ampoule wants to float ( buoyancy ), producing opposite forces . Since timer has smaller diameter than tube, the timer can tilt side way. Because of previous opposing force, the timer wants to spin. This spinning force causes each ampoule to push on walls of tube, causing friction.
      This side friction linked with small angle is used in many wood working tools, including hand press, or maçonnerie press.
      Any basic glass will present suffisant friction, as long as it's cheap ( not industrial polished ).
      As tip, the video reminds the tube has much larger diameter than the timer.
      Surface tension between glass and liquid matters. The liquid must not prevent sticking.
      When half sand is gone, both ampoules have equal buoyancy, and spinning force is null. Friction does not exist any more.
      You use the same principle when you climb between two narrow walls ( very close buildings, or narrow corridor ). Gravity or buoyancy can be fighted by suffisant lateral friction with angles.
      Same principles( but opposite direction ) when using dry wall or plank lifter, ice lifter, or concrete block lifter. All those clamps work the same .

      My guess is it has something to do with the pressure of water increasing as you go deeper. So when the air is at the bottom, it is experiencing slightly more pressure. So I think there is a diaphram in there or the hourglass is plastic... and is compressed when under pressure. When the air rises it is under less pressure and expands, making the hourglass 'lighter' since it has more empty space.

      @@GregMoress inside the sander, the pressure is the same everywhere. It's too small to show a pressure difference between top and bottom. The différence of pressure induced by the difference of height of water is all absorbed by the glass of sander, and does not replicate to the inside of sander.
      It could have been true if there had been difference of temperature. It's not for a difference of pressure on very small objects.

    2 Why it spins is because of careful balancing of repel / attract magnetic forces. What happens if you put the ball with the blank side up?

    • @julianm12345
      @julianm12345 2 місяці тому +5

      My guess is that when turned upside down the weight of the sand is in the top section so the hourglass rotates slightly pushing the top section against the wall. And when trying to float up it pushes more against the wall. As the sand drops through, the bottom becomes heavier and the top section is able "float" to be straight above the bottom half, and so can now float to the top.

    You should add a warning.
    I tried shining the light from a Sonic Photonic Visualizer through a CUMOS Cube while playing "Princes of the Universe" at full volume. It opened up a portal to a parallel dimension, some dude with a sword came through and tried to cut off my head. Fortunately, due to the size of the CUMOS Cube, the guy was only 1/4" high so it was pretty easy to smash him. 🤪
