Chroma by Mark LemonYour browser does not support the video tag. In the world of magic, the best tricks are often the simplest. Mark Lemon's "Chroma" is elegantly simple, but deceptively powerful! Stroop Tests. You've seen them across the internet, but probably have had no idea what they're called. Chroma disguises itself as a basic Stroop test designed to test cognitive ability. But this is all you need to reveal the thoughts that only exist in your spectator's mind

Great Product for noise reduction in Auto Use.
Model: 36 SqFt(3.4 SqM)
I use this on many builds to dampen the metal echo in cars, vans, and trucks. Just one sheet in the center of a body panel is a huge difference maker. You can also cover the entire surface and get added insulation value. The noise is greatly depleted and it's easy to install with a roller tool. Looks Great when done. Good Product I will use again!
