Forensic

If you ever watch CSI you'll noticed that for making a fingerprint visible they do something called fumigation. For this they need a chemical compound called cyanoacrylate. It's a usual chemical compound we found in our daily life, since it's the major compound of Super Glue. In CSI, they heating this chemical compound and then the fumes come out and make the fingerprint visible. Then, how this trick works?

Tricky Chemistry

Have you ever seen how a mere water turns into wine? Well, of course it's not like in Bible. It's just looks like the water transform into wine, or that's how you saw it. I found this article about simple magic trick that using chemistry as its basic. It using some sodium carbonate and pH indicator called Phenolpthalein to do this trick. The article itself has explained how it could happen. But let's see it more deeply than just a how-to. Welcome to the tricky chemistry :) .
