"Spiders float in the air using electric fields" might be a better title. I initially thought this was going to be a detailed explanation of how spiders use water's surface tension (due to water's electric dipole) to float on ponds. This article is actually about "ballooning". Here's an excerpt from the abstract:
> To disperse, spiders “balloon,” whereby they climb to the top of a prominence, let out silk, and float away. The prevailing view is that drag forces from light wind allow spiders to become airborne, yet ballooning mechanisms are not fully explained by current aerodynamic models. The global atmospheric electric circuit and the resulting atmospheric potential gradient (APG) provide an additional force that has been proposed to explain ballooning.
I've left out some of their in-line references.
