A stone bouncing across the water looks like magic. But you don't need a wand—just plenty of practice.
Steps
Go to a Body of WaterHead for the shore of a pond, lake, or slow-flowing river.
Find a StoneFind a smooth, flat stone that easily fits in the palm of your hand.
Hold the Stone ProperlyHold the stone flat, with your thumb on top and middle finger below. Curl your pointer finger around the stone's edge.
Throw the StoneThrow the stone toward the water. Snap your wrist forward when you release the stone and spin it off your pointer finger. The faster it spins, the better it will skip.
Count the SkipsCount how many times your stone skips before it sinks. Then see if you can beat your record! (Can you believe that the current world record is 51 skips in a row? Wow!)
