Build Micro-hydro Generator

Safety Precautions
Electric drills can cause serious eye and hand injuries. Eye protection is required, and leather gloves are recommended when drilling small parts such as corks. A corks borer can be used as a substitute but it also has risks for injury.
Hot glue guns can cause superficial burns. Be sure glue guns are warmed up only when needed, and unplugged immediately after. Hot glue can stick to skin and clothing.
Utility knives can be hazardous. Expose only as much blade as you need to cut the material, and fully retract the blade when not it’s not in use.
