(PhysOrg.com) -- Ornithologists first put forth the theory that hummingbirds took in nectar using capillary action (where liquid rises against gravity in a narrow tube) in 1833 and since then no one ...
When you water plants, you water their roots. But how does the water travel all the way from the roots of the plant to the leaves? They are standing upright: wouldn’t that defy gravity? In fact, there ...
On July 9, we explored the science of capillary action in our new kids video series: Summer School with Live Science. In this week's installment, Live Science producer, Diana Whitcroft, will ...
Researchers previously thought tube-like channels in their tongues sucked up fluid by capillary action. But the new analysis shows that their tongues actually trap nectar by curling around it. With ...
Introduction How do trees suck water all the way up to their leaves? How do paper towels soak up a spill? Are these things related? Try this project to learn about capillary action, and repeat a ...
PITTSBURGH (KDKA) -- Candles are neat, calming to some and full of science. They are made of wax and a wick which seems pretty simple. Once you light the candle, the wick burns. As the wick burns, it ...
Carbon nanotubes, despite all the technological advances they’re making possible, look pretty boring. When viewed though a microscope, they are, essentially, just straight tubes. Now scientists from ...
