PITTSBURGH (KDKA) -- If you think about it, water can be kind of weird. It can be a liquid, a solid or a gas. It contracts when it is cooled to a certain point, then starts to expand as it gets closer ...

Here’s an easy experiment with pepper and soap that allows you to see surface tension – and its destruction. Photo by John Bush, Tristan Gilet/MIT. Shake some pepper, carefully, into a cup of water.

Water has very unique properties, and this experiment puts them to the test! Follow along with ABC11 Science Club with BASF and discover how to measure surface tension using a simple penny! Objective: ...

Whenever you see open water (either running or still), you can often feel a little closer to your primordial roots — after all, life (and that includes you) came from the oceans. And so, whenever you ...

Fill water dropper with water Add one drop at a time onto the penny Watch what happens EXPLANATION: Have you ever seen a bug walk on the water? This is because of surface tension! Water is what we ...

Surfactants play a pivotal role in modifying the interfacial properties between polymers and liquids. By adsorbing at both the liquid–air and polymer–liquid interfaces, these molecules can reduce the ...

Take a moment to imagine a warm summer Vermont day - they’re coming soon! You have the luxury of jumping into a pool to cool off. As you hit the surface it feels kind of hard but you splash in and ...

Ever wonder what trees, water skimmers and laundry detergent have in common? It turns out that the physical concept of surface tension is essential to their function. The idea behind surface tension ...

Nothing beats kitchen science for fun. I recently filled a glass of water to the brim. Then little by little, I added extra water from a teaspoon until I raised the level until it was clearly higher ...

1. Pour enough water into a shallow dinner plate to just cover the bottom - you don't need more. Sprinkle fine ground black pepper on the water. 2. The water will look something like this. 3. Dip a ...

Biological tissues exhibit two contradictory properties: they have a robust architecture that is required for their maintenance and resistance to stress, and they can be extensively remodelled during ...

For many cloud-forming water droplets, it’s what’s on the outside that matters. By making their own clouds, scientists have discovered a new way that fat water droplets take shape. Carbon-containing ...
