WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
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.
