The second sandfountain came to be from an imagined ideal situation in which the machine could continue spewing sand endlessly. This would function in the following manner: There is a circle of sand, surrounding a standing object in its centre. A wooden beam is placed on top of this object, one side of which holds a screen that consists of two transparent sheets of material on small wheels. The other side of the beam supports an engine that is connected to two wheels, one parallel to its axis and directly attached to it, and one which is placed perpendicular to its axis. This second wheel allows the construction to rotate around the centre of the installation, following the circle of sand. The other wheel which is directly attached to the axis spins rapidly while moving through the sand. This causes the sand to be flung away, along the direction of the crossbeam, towards the screens. As the screen is attached to this crossbeam, it is always in polar opposition to the wheel which flings the sand, blocking it. Having hit the screen, the sand falls back to the ground, only to be flung away again when the spinning wheel reaches the other side of the circle again, ad infinitum.
