Gas pressure is often introduced through familiar objects—a balloon, a tire, a carbonated beverage, or a sealed container—but its behavior is governed by a consistent physical principle: gas particles in continuous motion transfer momentum when they collide with a boundary. When a gas is trapped, those particles cannot disperse freely into the surrounding environment. Changes …

I'm a "dirt-ologist". I love studying the interface of human and environment interaction, often asking the rather rhetorical question: "Do we change the landscape, or does the landscape change us?"
I also captain the ISS Insanitekian, a startup adventure of a lifetime.
The Science of Biomes: Helping Students Understand Climate vs. Weather
Everyone already teaches the water cycle. Most textbooks and museum exhibits stop neatly at evaporation–condensation–precipitation—a tidy loop that explains where rain comes from, but not why some places stay dry while others are drenched year‑round. At Insanitek, we like to go one step further. The same ideas that drive the water cycle—energy from the Sun, changing temperatures, and …
Why Hands‑On Science Matters More Than Perfect Labs
In the mass‑acceleration lab at Purdue, we had a pyramid made of duct tape rolls—nine to a level, stacked into a 3×3‑foot base. Halfway up was a note that read, “Order more duct tape.” We grinned like lunatics every time we saw it. It wasn’t art—it was infrastructure. That tape kept the mass accelerator patched, …

How Robotics Builds Problem‑Solving and Engineering Mindsets
How robotics teaches problem solving and engineering comes down to how you structure the work: real problems, real constraints, and time to iterate, not just “drive the robot around.” Why Robotics Is More Than “Playing With Robots” When kids and teens build and program a robot to do a specific job, they have to break …
Independent Environmental Testing for Small Farms and Homesteads: Affordable Soil and Water Testing
Independent environmental testing gives small farms, homesteads, and community gardens a reality check on soil and water quality so you can grow food safely, use inputs wisely, and catch problems before they become crises. It works alongside extension offices and big labs by adding a neutral, client‑focused partner who can ask “but what does this …
How to Choose Lab Glassware on a Budget (Without Regretting It Later)
If you’re trying to do real chemistry with real constraints, you don’t need a catalog’s worth of gear—you need a small, tough core kit and a plan for upgrading over time. This guide walks you through what’s truly essential, what you can improvise, and which pieces are worth the “buy once, cry once” treatment. Start …
How a Liebig Condenser Really Works (So You Don’t Flood the Lab)
Editor’s note: Most of the foundational work on condensers and on Justus von Liebig’s teaching laboratory was published in German, where Liebig lived and worked as a chemist and professor. Many of those primary sources have never been translated or made easily searchable online, so what you see below leans on peer‑reviewed articles, museum archives, and …
How a Small R&D Lab Helps You Test Ideas Without Building Your Own Lab
You know something needs testing—your town’s water looks off, a prototype keeps failing, or a process “just feels inefficient”—but you don’t have a lab, a scientist on payroll, or time to figure it out alone. Instead of building an in‑house R&D department, you can hire a small, nimble lab for the specific questions you need …
Yellow Water in Lapel: How a Small Lab Can Support a Community Already Fighting
In Lapel, Indiana, people are turning on their taps and seeing bright yellow water flow into their sinks, tubs, and baby bottles. Residents describe it as “fluorescent” and “the color of sweet tea,” and photos circulating online and in local coverage are hard to look at if you imagine bathing your kids in it. Brianna …
Avoid These Simple Machines Mistakes: Common Misconceptions About Work and Mechanical Advantage
Picture this: You’re watching a student’s eyes light up as they use a pulley system to effortlessly hoist a heavy bucket. “This machine takes away work!” they exclaim triumphantly. You smile—they’re engaged, they’re excited—but there’s a problem. They’ve just locked in one of the most persistent misconceptions about simple machines, one that will muddy their …
