Skim stones at a lake or river

Stone skimming looks like luck and is not. There is a genuinely optimal technique, studied by people with high-speed cameras, and it comes down to a flat stone thrown fast and low with plenty of spin, striking the water at roughly twenty degrees. To skim stones at a lake or river well is a matter of copying that.

Why skim stones at a lake or river is worth an hour

The stone bounces because its underside deflects water downward, and the angle determines whether it skips or dives. Around twenty degrees is the sweet spot. Spin is what keeps the stone at that angle through the flight, exactly as a spinning frisbee stays level, which is why a wobbling stone loses its attitude and stops after one bounce.

How to skim stones at a lake or river step by step

1. 1

   Choose a flat stone with some weight

   Roughly palm sized, flat, with a slightly rounded edge. Too light and the wind takes it.

2. 2

   Hold it along your index finger

   Thumb on top, index finger curled around the edge. That finger is what imparts the spin.

3. 3

   Throw low and fast

   Almost sidearm, close to the water. Height is wasted energy; speed and lowness are what matter.

4. 4

   Flick the wrist for spin

   The snap at release is the whole technique. Spin keeps the stone level through the flight.

5. 5

   Aim for a shallow angle

   Around twenty degrees to the surface. Too steep and it dives, too flat and it loses energy immediately.

Tips to get more out of it

• Calm water skims far better than choppy. Wind ripples break up the bounce almost immediately.
• Check what is under and beyond the water first. Swimmers, wildlife and shallow rocks all matter.
• Avoid disturbing nesting birds on shorelines, particularly in spring.

Ways to mix it up

If you want to compete with yourself, count bounces rather than distance; they measure different things and bounce counts improve faster. If the shore has no flat stones, this is one of the few activities genuinely defeated by the wrong location, so try somewhere else.
