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 bugs2 are so light, speeding water drops simply brush them aside without imparting much force. The results are appearing the proceedings3 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 hitches4 a right for bit, before peeling off unharmed.
