The maker movement is making science exciting again. Forget the lame baking soda "volcanoes" and the zillion-dollar supercolliders -- just as punk rock took music back from the supergroups and big studios, "punk scientists" are making inexpensive new tools to conduct real experiments in garages, schools, and hackerspaces. In MAKE Volume 31, you'll learn how to make DIY laboratory equipment (even a scanning electron microscope!), create high-voltage sparks from falling water, control a cockroach electronically, get started in biotech, and see how individuals and schools are networking their data for real scientific discoveries. Plus: Get started with multicopters or servo controllers, and build an automatic dog ball launcher, great-sounding speakers with flashing LEDs, a classic folding-wing Rocket Glider (a new MAKE kit), an iPad music desk, a levitating solar Mendocino Motor, and much more.
