''#Spiders have been found two-and-a-half miles up in the air, and 1,000 miles out to sea.''
''It is commonly believed that ballooning works because the silk catches on the wind, dragging the spider with it. But that doesn’t entirely make sense, especially since spiders only balloon during light winds.''
''spiders can sense the Earth’s electric field, and use it to launch themselves into the air.''
