This is Scientific American's 60 seconds science. I'm Kellen Horgon. This will just take a minute.
Have you ever wondered what happens to mosquitos in the rain, a raindrop is like 15 times heavier than those little suckers. So getting hit by one, he's got a hurt, right? Well, not so much. Because researchers at George Tech found that the bugs 2 are so light, speeding water drops simply brush them aside without imparting much force. The results are appearing the proceedings 3 of national academy of sciences. Previous days have shown the precipitation can be a real pain for a lot of winter craters(winged critters), that has spend twice as much energy of flying through the storm than in a clear skys. But what about bugs no bigger than the raindrops themselves. Researchers use high speed video to watch mosquitos went in the rain, more through a spray of mist in a lab. They saw when a mosquito in waterdrop meet, the insect basically hitches 4 a right for bit, before peeling off unharmed.
so, the bugs go with a flow and offer a little resistance, and the drop slow is only slightly, keeping its kinetic 5 energy rather than the blasting the bug 1, so for storm trooping mosquitos, resistance is not only futile 6, it's all wet.
