If you like to tweak, disassemble, recreate, and invent cool new uses for technology, you'll love MAKE, our project-based quarterly for the inquisitive do-it-yourselfer. MAKE Volume 07 is the Backyard Biology issue, with DNA extraction, plant grafting, home mycology lab, snail cryogenics, and more. Also, learn how to make your own Stirling engine, install a video camera on a model rocket, make a head-mounted water cannon, and dozens of other projects to satiate your inner maker.
