Harness the power of the wind, lemons, potatoes or mud. The Windmill Generator has a generator and propeller with (6) 5-3/8” wide blades and a tail. Minimal assembly is required to mount them on a large soda bottle (easier than building a tower, but you could do that, too) and watch the wind light up the LEDs. The Enviro-Battery Kit has copper and zinc plates, cups, an LED monitor on a little tower, sound module, LCD clock plus wire and tape. You perform (6) different battery experiments, plus many more suggested in the included book, and yes, a mud battery is among them.

We're really charged up about this modular Electronic Lab from Maxitronix(tm) that appeals to both girls and boys. The 4-in-1 set of interactive action kits includes colorful 5-1/2" x 3" x 1-1/8" plastic housings and components to build an electric bell, motor, generator and meter. As the manual says, they're "safe, solderless, educational and fun!" And the manual is the best we've ever seen. Every part and every step is illustrated and labeled (it doesn't presume you can tell an egg lug from a tapping screw), and it explains HOW each experiment works. Kids trying out the 10 suggested experiments learn to reverse a motor's direction, operate the bell or motor with the generator, use the meter to measure electricity and more. Requires (2) "AA" batteries (not included). This is an exceptional set for boys and girls aged 10 and up.
