Cornstarch can thicken soup or serve as a base for a DIY shampoo, but there's more to the humble pantry staple. Given the right conditions, it seems to defy the laws of physics. Mixing cornstarch with ...

Each week, we bring you a quick and easy experiment you can do at home to explore a concept in science. This week, we’re ...

Mixing corn starch and water in appropriate amounts produces a slurry that is liquid when stirred slowly but hardens when you punch it—a substance colorfully dubbed “oobleck.” (The name derives from a ...

Oobleck has long been my favorite example of a non-Newtonian fluid, and I’m not alone. It’s a hugely popular “kitchen science” experiment because it’s simple and easy to make. Mix one part water to ...

You may be familiar with a common science demonstration done in classrooms: If you mix cornstarch and water together in the right proportions, you create a gooey material that seems to defy the rules ...

It takes guts to attempt running across the surface of a liquid. Even more so if a sneaky physicist is nearby. Oobleck is a non-Newtonian fluid, meaning that its viscosity changes depending upon the ...

Lots of people have demonstrated that, surprisingly, if you fill a pool with water and cornstarch you can run across it. Stop, and you sink. How that happens, though, has been something of a mystery ...

It's a phenomenon many preschoolers know well: When you mix cornstarch and water, weird things happen. Swish it gently in a bowl, and the mixture sloshes around like a liquid. Squeeze it, and it ...
