Discover the mystery that goes on the water

Walking on the water seems to be a miracle to humans, but it is normal for water beetles and scientists have also discovered the mystery of this miraculous ability. Now Korean researchers are giving a long-held explanation of the water bug's ability to jump on a surface of the solution without sinking.

In this new study, Ho-Young Kim and Duck-Gyu Lee noted that scientists have discovered the water-repellent properties and structure of the water beetle's legs and that these characteristics helped How quickly water bugs flutter on calm lakes. However, the ability to jump or glide over the surface of the solution is still a scientific mystery.

They found that the ball had to roll away at a small velocity range to glide out of the water. Drops of solution will sink if it moves too fast and will not bounce back if it moves too slowly.

The authors said that the high improvement of the strong waterproof solids to maintain floating on the water or even after the high impact on the water at high speed seems to explain somewhat. The reason why water beetles have extremely super waterproof feet.'Our research application can be extended to invent underwater semi-robots that can mimic this insect with the ability to move on water.'

The article ' The effect of an ultra-high waterproof ball on the surface of the water ' was published in the Langmuir of the American Chemical Society (ACS) released December 18.
