Popular Science’s How 2.0 has a round up of Theodore Gray’s articles from the past 3 years, tons and tons of experiments and how-tos – ” Ever yearn to make your own silicon? Preserve a snowflake on a microscope slide? Fuel a rocket ship with sugar? Theodore Gray undertakes these and many more mind-bending projects in his monthly PopSci column, archived here for your entertainment. Just remember that Gray is well trained in lab safety procedures–if you decide to try these experiments, you should be, too.” – Link.
