Wonderful little book jammed with elaborate colored drawings that tells the beginner a little about everything to do with a microscope. And all in a mere 48 pages! From data on the history and types of microscopes, to introductions and samples and how to prepare them, (from tissues and insects to crystals) to ideas for experiments and lists of simple equipment needs, and how to build them at home, this book is a veritable cornucopia of information. If you are thinking of getting a microscope, we strongly recommend "The World of the Microscope" as a great stimulus for the novice user. It won't answer heavy duty scientific questions. But it will keep the beginner busy, challenged and entertained for days and weeks! By Chris Oxlade and Corrine Stockley. Paperback, 7-3/4" x 9-3/4". One of the Usborne science and experiments series of books.

Not every well-made rotary tool is a big-D. We consider this one not only a good-quality tool, but an excellent buy. The fitted plastic carrying case 12" x 8-1/2" x 3-1/2" contains not only the 120VAC-powered 8,000-30,000 rpm mini grinder, but a stand with a C-clamp to mount it on a bench or table, a 3-ft extension shaft, and a good assortment of bits, grinding stones, cut-off wheels, etc, including collets to fit 1/8" and 1/16" bits. The telescoping stand extends from 10" to almost 22" and holds the tool above your work, while you grind, sand, cut, etc., with the tip of the convenient, easy-to-grip, flexible extension. A nice package, and a very nice gift for yourself, or for anyone who enjoys working with hobby tools.

This clear cellophane tape is twice as sticky -- it has adhesive on both sides! It's flat, like that narrow tape that comes with the famous plaid label, but it's 3" wide. The roll is 21-3/4 feet long on a 1-1/2" core. Great for bigger jobs.

Why does it do that? Develop an elemental understanding of magnetism, electromagnetism, electrochemistry, radio, thermodynamics, light and optics. Simon Quellen Field's 228-page paperback, Gonzo Gizmos, Projects & Devices to Channel your Inner Geek explains processes, equipment and scientific terms -- and then, for starters, tells you things like how to make a rotary steam engine in 15 minutes from a soda can, a candle and a few scraps of rubber tubing. It's the favorite of our resident geeks -- but not for kids unless they're working with an adult. That would be a mature adult. An insured, mature adult.

Small, but mighty useful if you need a tiny tap and die set for threading wire or stripped screws. The micro set has a 3-1/4" long die plate and 14 taps (sizes 7 through 20 -- read 0.7 mm through 2.0 mm), and a mighty attractive price. A little oily in its vinyl storage pouch -- but it's all steel, after all, and has to safeguard its complexion.
