No — cliff jumpers don’t throw rocks reduce the water surface tension to soften the impact at landing. Here are the five real reasons why we do it : 1) Calibrating height. From above, it’s surprisingly hard to judge how high a cliff actually is. By watching the rock’s airtime, we can estimate the height of the jump to within a few meters and adjust our timing accordingly. 2) Checking the gap. Sometimes the water isn’t directly under the take-off — there can be a horizontal distance to clear. We
