The Pocket Chemist is an incredibly useful, double-sided stencil and chemistry reference.

Despite accusations, I am not paid by Big Pharma, The Illuminati, or even The Stonecutters (they keep the metric system down, you know) to write this blog.

I do, however, get a little kickback from the lovely people at Genius Lab Gear every time you buy one of these fabulously-useful Pocket Chemists.

There’s a blog post with more photos here.
