So easy to understand!It's the same principle as skipping a stone.I also want to try!That isn't a problem, howeverIt is said that for a stone to skip well, it requires an initial speed of about 90 kilometers per hour, hit the water at an angle around 10 to 20 degrees, and be spinning at a rate of approximately 30 revolutions per second.A human leg is limited to rotating about 90 degrees, however if you can rotate your leg within 0.008 seconds, you can achieve force equal to doing 30 full rotations.That isn't a trick.After that it's a matter of minding the angle you hit the water, maintaining your speed, and estimating your mass ratioUm, basically, if you go forward with your left foot before your right foot sinks you'll be able to run on water.I see!What?!Ogawa-san, can you teach me that trick you used before for running on water?
