When I think about plants, "hairy" is not the first word that comes to mind. But it turns out that most plants do grow lots of little hairs--technically called "trichomes" and also, technically, more like cilia than hair--and those hairs are usually water-repellant, causing raindrops to bead up on the plant's leaves like water on a windshield.
But scientists have discovered that the hairs on Heliamphora nutans, a species of carnivorous pitcher plants, have the opposite function: they are supremely wettable, causing water droplets to spread and turning the surface of the funnel-shaped plant into an inescapably slippery trap:
And here's one more quick clip showing how water spreads over the plant's surface:
Other carnivorous plants have specialized hairs that stick to prey, trigger trap movements, and absorb nutrients, but Heliamphora nutans is the first plant known to have developed the death-by-waterslide trap.
Oooooo, drat that slippery wet carnivous plant!
This article sucks. The way those videos work...sucks. Shame on you popsci. These videos have the worst kind of advertising with pop open windows.
