The Beetle Who Is a Chemist

On today’s Creation Moments Minute, a beetle that moves across the surface of water without any body movement at all.

Like many other insects, the large-eyed rove beetle can walk on water. Should you see one, you’ll notice that he moves across the water, stops, turns, and starts up again without moving any part of his body. How does this work?

The beetle has special glands that produce a chemical – something like detergent – that changes the surface tension of the water. When the surface tension of the water near his back feet is different from the surface tension near his front feet, the beetle is pulled forward.

Such a unique method of movement requires sophisticated knowledge of both hydrodynamics and chemistry. It makes a lot more sense to talk about a wise, personal Creator than it does to speak of the wisdom of a mindless force like evolution.
