It can look dumb, but I always had this question as a kid, what physical principles would prevent this?

    The motion of the stick will actually only propagate to the other end at the speed of sound in the material the stick is made of.

      So when you pull on the stick and it doesnt immediately get pulled back on the other side, you are, at that instant, creating more stick?

        You know what’s more crazy. Electrons don’t flow at the speed of light through a wire. Current is like Newtons Cradle, you push one electron in on one side and another bounces out on the other side, that happens at almost light speed. But individual electrons only travel at roughly 1cm per second trough a wire.
