News Release – LOGAN, UTAH, Nov. 2, 2016 – It’s a common swimming pool game: Force a buoyant ball underwater and let it go. The ball springs to the surface and jumps into the air. But, submerge the ball deeper underwater and the effect is often disappointing. Contrary to intuition, increasing the release depth often leads to a decreased pop-up height.
