Can water droplets be cut in half? Cattleman tested with a blade, interesting scientific phenomenon occurred!
Foreign guys strange experiments, cutting water with a blade? Draw a knife to cut off the water, the water does not flow?
Take a look at the strange experiments of foreign guys!
Today's foreign guy's brain hole, as always, is as clear as ever, actually thought of using a knife to cut water droplets, with our normal thinking, water droplets will definitely stick to the blade, or when the blade leaves, the water droplets on both sides are re-fused together, we see how this foreign guy does it?
First of all, he placed the two thin wires well, adjusted the distance, and then used the dropper like these two wires to drip water, the dropper can control the size of the water flow very precisely, after the water droplets on both sides are connected together, the distance between the two thin wires is stretched far, the water droplets have become long strips, and then it is the highlight of the whole experiment, the guy took out an ordinary wallpaper blade, a knife cut the water droplets, when the knife was lifted, the water droplets did not stick to the blade, and did not re-fuse together.
After this guy dropped a few drops of water on the paper, with a blade to cut, although when cutting water droplets, because there is no fixation of water droplets, so the water droplets will run around, but once cut to or will be cut off a piece, and then the guy added color in the water, so that the experimental effect is more obvious, the hand knife fell is also the water droplets smoothly cut open, in fact, often pay attention to the small partner of scientific and technological invention, should be able to see the end, the foreign guy This knife cut off the water skill, is because it is on the surface of the blade and the surface of the paper, Sprayed with a superhydrophobic material.
Although blades and paper are common goods, but superhydrophobic materials can allow them to form a hydrophobic layer on the surface, the development inspiration of this material is from the lotus leaf, the lotus leaf has a strong self-cleaning function, the reason is that its surface has wax grease and super small bumps, so small that the eye can not see clearly, which makes the water droplets that fall on the surface of the lotus leaf, and the lotus leaf surface form a layer of air isolation layer in the middle, so that the water can not be adsorbed on the page of the lotus leaf, and when the water flows, it is easy to roll away the dust on the leaf surface.
I have to admire the magic of nature, and the creativity of foreign guys, next time find interesting foreign guy experiments, and then do a foreign guy strange experiment video for everyone.
