A gathering of specialists at the Seoul National University has made a machine that can hop on water. Its standards are in view of the bug water strider, that can sit and even hop on water. It is the basic material science that these creepy crawlies utilize so smoothly. The bugs have the knowledge of the surface strain of the water, that may be evading the greater part of us. Surface strain is the property of the fluid by which it opposes an outer power because of the strong strengths between the fluid’s particles. Essentially, surface strain permits the fluid to “stick” to itself. Presently, the creepy crawlies push down on the water with most extreme drive that the surface strain can take. More prominent is the push, more is the surface strain that is manufactured under the leg-and better is the upward bounce on water. The water strider accomplishes this equalization by pivoting its center and rear legs while pushing them downwards to fabricate enough force for a jump. The same guideline is utilized as a part of this lightweight robot. The outline is like the water strider, yet it has 5 cm longer legs to amplify the torque. It is like bouncing on a strong ground, which can sink on the off chance that you apply a lot of weight. Along these lines, in fact on the off chance that you could adjust your weight with the surface pressure of the water or any fluid so far as that is concerned, you can stroll on that fluid. Subsequent to perusing this, you may not think it as a noteworthy accomplishment when contrasted with a just about affirmation to a conceivable EM Drive or ascent of the AI that appears to be undermining to Stephen Hawking himself. In any case, this little analysis clears the hypothetical comprehension that physicists dependably had, and could lead in future an innovation, that can permit people to stroll on water. https://youtu.be/QjtI8WAUFDs
