In this Test Tuesday, we tested Sharpie permanent markers on different foam board samples to see how they perform in real use. The markers showed clear results on every surface, with the strongest visibility on white boards and more varied effects on colored boards, including a subtle iridescent look on black premium foam board
Why do 1 in 3 markers leak before use? In many cases, marker leaks happen because of heat, temperature changes, loose caps, damaged nibs, over-shaking, improper storage, or pressure shifts during travel, while some “explosions” are more often caused by warm hands, tight gripping, and hot environments that make the ink expand and flow too freely. Darker colors may be more prone to this because they contain less solvent, and overfilling can also cause dripping. To reduce leaks, store marker
One school found a practical way to save $12,000 a year by taking a closer look at everyday operations and cutting waste where it mattered most. Instead of making one big change, it focused on small, smart improvements—tightening energy use, reducing unnecessary spending, improving maintenance habits, and using resources more efficiently. The result was a meaningful annual saving without hurting student experience or school quality. This case shows that with the right strategy, even a modes
What if your highlighter could last 3x longer? With the right choice and care, it can stay bright for months—or even years—without drying out. Instead of buying cheap bulk packs, start with a few high-quality highlighters featuring sealed caps, anti-dry technology, refillable ink, dual tips, and acid-free, UV-resistant form
Is your marker ruining your presentations? The main message is that a presentation is weakened when slides are overloaded, poorly designed, or used as a crutch. Effective presentations should be built around a clear objective, a strong opening, and a simple structure that fits the audience. Slides work best when they are minimal, visual, and purposeful—one idea per slide, short cues instead of long paragraphs, readable text, consistent fonts and colors, and high-quality images that support
“87% of classrooms switched—why haven’t you?” is a sharp challenge to the idea that schools have stayed unchanged for centuries. In reality, classrooms have already shifted through technology, testing, and EdTech investment, but many of those changes are surface-level and have failed to improve learning in meaningful ways. The deeper issue is not a lack of change, but the wrong kind of change—reforms driven by trends and corporate interests rather than evidence, coherence, and stude
If your whiteboard is sticky, smudgy, or fading, the problem may not be the markers—it may be the board itself. This article shows how to bring an old, heavily used whiteboard back to life: start with a dry eraser, scrub stubborn stains with toothpaste and a washcloth, wipe the surface with isopropyl alcohol until it feels smooth, and finish with a light coat of WD-40 to help reseal the board and reduce future staining. The method is meant only for old boards, since it can damage the coatin
Why do 94% of teachers ditch cheap markers? Because while whiteboard markers help save time, reduce paper use, and ease student anxiety, low-quality ones usually dry out fast, write inconsistently, and end up being wasteful. That’s why many teachers choose a better alternative like Pilot V Board Master Markers. They deliver b
