Claim:
A bubble top, comprising: a water-tight tank, comprising: clear top surface having a width W 1 and a length L 1 ; a first bottom surface separated from the top surface by a first height H 1 , the first bottom surface having first and second parallel primary sides each with a length L 2 and first and second parallel secondary sides each with a length W 1 , L 2 being less than L 1 ; a second bottom surface separated from the top surface by a second height H 2 greater than H 1 , the second bottom surface having a width W 1 and a length L 3 =L 1 −L 2 ; a first set of sidewalls connecting the top surface with the first bottom surface; a second set of sidewalls connecting the top surface with the second bottom surface; and a third set of sidewalls connecting the first bottom surface with the second bottom surface; whereby the second bottom surface and second and third sets of sidewalls form a reservoir; a water pump having: an inlet coupled to receive liquid from the reservoir; and an outlet to force the liquid into the tank; first and second tubes, each coupled to the outlet of the water pump, the first tube extending horizontally between the top surface and the first bottom surface and adjacent the first primary side; the second tube extending horizontally between the top surface and the first bottom surface and adjacent the second primary side; first and second pluralities of third tubes, through which water is ejected into the space between the top and bottom surfaces, the first plurality of third tubes being coupled to spaced-apart openings in the first tube and extending horizontally between the top surface and the first bottom surface perpendicular to the first tube; and the second plurality of third tubes being coupled to spaced-apart openings in the second tube and extending horizontally between the top surface and the first bottom surface perpendicular to the second tube; the reservoir and a lower portion of the space below the top surface and first bottom surface being fillable with the liquid whereby, when the pump is activated, the liquid is pumped from the reservoir through the first and second tubes and out ends of the first and second pluralities of third tubes into a space between the top surface and first bottom surface, whereby further bubbles are formed and move within the space between the top surface and first bottom surface.
