New Plastic Coating Will Let You Get Every Last Drop of Shampoo Out of the Bottle New Plastic Coating Will Let You Get Every Last Drop of Shampoo Out of the Bottle

Getting that last bit of shampoo or detergent out of a bottle is a total pain in the ass. Researchers have now engineered a surface coating that allows thick and soapy products to slide right out—meaning you’ll never have to store your shampoo bottle upside down ever again.

Studying These Bugs Led Researchers to Discover an Entirely New Mode of Insect Flight Studying These Bugs Led Researchers to Discover an Entirely New Mode of Insect Flight

If the waterlily beetle were the size of a human, it would fly along the surface of a pond at 500 kilometers an hour. Then again, if a waterlily beetle were human, it wouldn’t fly at all. The beetle is subject to, and able to take advantage of, forces we don’t even notice—and when scientists did notice, they realized…

Pent-Up Energy Causes Drops to Hurl Themselves Off a Teflon-Covered Thread Pent-Up Energy Causes Drops to Hurl Themselves Off a Teflon-Covered Thread

When you see a droplet resting on a counter or coalescing around a thread, you don’t generally think of it as a coiled spring, but under the right circumstances that’s what it is. In this video, we can see how the spring releases.

Incredible Robotic Water Strider Jumps Like the Real Thing

Researchers from South Korea have created a robotic insect that’s capable of jumping and landing on an aquatic surface, a unique mode of transportation found only in specialized animals.

Dumping Oil In the Ocean Lets You Literally Master the Waves Dumping Oil In the Ocean Lets You Literally Master the Waves

Oil in the ocean is a sensitive subject these days, but in the late 1800s, steam ships had stocks of oil specifically set aside to dump in the ocean. This may have saved people's lives. We'll tell you why.

Behold, the Dazzling Magic of Surface Tension Behold, the Dazzling Magic of Surface Tension

Ever wonder what makes water dance around your windshield the way it does? It's all a matter of surface tension: a simple set of rules that makes science sometimes look like art.

This image shows us what a perfect water droplet looks like This image shows us what a perfect water droplet looks like

This droplet of water describes a near-perfect sphere. It does this because the surface of the leaf does not allow for a lot of wetting.

These insects are touring a sunken flower city These insects are touring a sunken flower city

This amazing image of a daisy shows the blossom, and a group of dry insects, below the water level. It's a striking image of the power of surface tension.

We could watch this bouncing water droplet all. Day. Long. We could watch this bouncing water droplet all. Day. Long.

And now you can, too! FYFD explains the physics behind this mesmerizing clip, which comes by way of Kahp-Yang Suh of Seoul National university in South Korea.

Watch what happens when you wring out a washcloth in space Watch what happens when you wring out a washcloth in space

This is just excellent. ISS Commander Chris Hadfield was recently asked by high school students Kendra Lemke and Meredith Faulkner to demonstrate what happens when you wring out a waterlogged washcloth in space.

Ten more bets you'll (almost) never lose Ten more bets you'll (almost) never lose

We say "almost," because like many of the bets in Richard Wiseman's earlier bar-trick videos, a few of these are liable to get you punched in the face. (I'm looking at you, #4. Ten to ten? Really?)

Here's an experiment with nanostructures you can do in your (dusty) room Here's an experiment with nanostructures you can do in your (dusty) room

This is fantastic. In this video, we see slow-motion video of water droplets falling on a dusty surface. Because the dust is made up of a special metamaterial, the drops become locked into different shapes as they bounce.

Awesomely Perfect and Refreshing Example of Surface Tension Awesomely Perfect and Refreshing Example of Surface Tension

Missing the olympics? Trapped in the office dying to dive in a pool or the sea? Love physics? If the answer is yes to any or all of this questions, you will love this amazing image of a swimmer about to break out of the water. Expand for gorgeous detail.

The science behind a snake's poison bite, and why it's related to ketchup The science behind a snake's poison bite, and why it's related to ketchup

We assume that snakes kill with venom shot through their fangs, injection style. In fact, most snakes leak poison very slowly. Oddly this technique works quite well, and you can figure out why by considering the physics of ketchup in a bottle.

The science of leaving ominous messages on bathroom mirrors The science of leaving ominous messages on bathroom mirrors

Scribbling on a steamed-up mirror can be a fun way to give one's reflection a mustache after a warm shower or leave death threats in horror movies. But what's the science behind it?

Here's an easy experiment with pepper and soap that allows you to see surface tension - and its destruction.

A Sunday morning primer on the joys of surface tension A Sunday morning primer on the joys of surface tension

A working knowledge of surface tension allows you to shove a skewer through a balloon without popping it and a pencil through a plastic bag full of water without spilling. Make your nieces and nephews think you're cool.
