Spiders can't fly, but with the help of wind and their silk threads they reach the stratosphere by 'ballooning'. Small spiders leave their bo****s very light silk, and a slight gust of breeze takes them high in the sky. This is how they can travel many kilometers away — sometimes above the clouds, even the height of airplanes! This is a nature-made air journey that requires air, not tickets. Where spiders hunt on the ground, they also travel the world in the air.
