The bumper returns to its original position after a collision. tank edge or clipped to it by threading a small polyethylene line through the tubing and attaching clothespins at close intervals. Adjustments were made at the tank flange to obtain a uniform, straight hanging surface all around the tank, and the ends of the tubing were overlapped with the inside lap folded back on itself. Spacing relative to the tank walls was accomplished by 13 )( 3 cm hard plastic seine floats strung end to end on a small Nylon line at the water level between the wall and the polyethylene tubing. During the last three experiments, the bumper system w-as modified by eliminating tank corners. In this case, the tipper edge of the polyethylene tubing was run at a 45° angle across each corner, thus excluding (in plan view ) four isosceles triangles 30 cm on a side from the tank'.
