Spiders can take off and stay airborne for thousands of miles, a process scientists have described as ballooning. The spiders propelled forward by trails of silk whether there is wind or not. They can take off with low levels of aerodynamic drag, contrary the laws of physics. How do they do it?

According to Current Biology published on July 5, 2018, biologists from the University of Bristol exposed Linyphiid spiders to the e-fields equivalent in strength to those found in the atmosphere. They observed that the spider moved upwards and downwards when they switched the E-field on and off respectively. This simple experiment proves that the spiders can take off without being assisted by wind.

Unlike humans, insects can detect Atmospheric Potential Gradients (APG). An APG is a global electric circuit that is always present in the atmosphere. Electric fields (E-fields) surround all matter and exert a charge on other things. Honeybees use e-fields arising between themselves and flowers to communicate with the hive and alert other bees to the presence of nectar.
