From Reactions. You’ve heard Yellow #5 can turn mice transparent, but how well does it work on people? We found the perfect, almost too willing, suspect to try this on. #transparentskin #mice #experiment #biomedicalresearch

From Reactions. That’s right, every other video you’ve seen about color has been wrong, or, at least, incomplete. Because they pretty much all say that when light hits an object, some is absorbed, whatever isn’t is reflected back, and that’s what we perceive as color. But absorption is not the whole story. This video is…

From Reactions. not sure why anyone would want to make everclear even stronger, but #distillation #alcohol #chemistry

From Reactions. This was testing the L-methamphetamine inhaler directly, not after metabolism, so maybe the test can distinguish between the metabolites but not the drugs themselves? If you have any other guesses, let us know. #organicchemistry #pharmacology #scienceshorts

From Reactions. Companies around the world are fighting to buy a rare radioactive substance, despite its $30,000-per-gram price tag. This substance powers emergency exit signs that can stay bright for two decades without power, glow-in-the-dark keychains, and might one day unlock the holy grail of clean energy. What is this mystery substance? Join George as…
