A bowling ball retention device for retaining a bowling ball from rolling comprising:
- a sheet of material having a thickness “t” and including a top surface and a bottom surface,
- said sheet having a plurality of through-holes each having an opening,
- whereby the diameter of the opening of the through-holes is a function of the thickness of the sheet material according the equation;
- D=2{square root}(2tR−t2)
- wherein D is equal to the diameter of the opening in the through-hole, “t” is equal to said thickness of the sheet material and R is equal to the radius of the bowling ball.
