A sand dispensing assembly is provided wherein two different sands are held in two bins in a top section. The bins are concentric and generally cylindrical. A middle section of the sand dispensing assembly includes a plurality of inner dispensing tubes at a first diameter from the center of the middle section and a plurality of outer dispensing tubes at a second diameter greater than the first diameter from the center of the middle section. A bottom of the sand dispensing assembly includes a plurality of discharge funnels. When the middle section is at a first position, sand fills the inner dispensing tubes from the first bin while sand exits the outer tubes through the discharge funnels. When the middle section is rotated to a second position, sand fills the outer dispensing tubes from the second bin while sand exit the inner tubes through the discharge funnels. |
