Windmill hub

DC generator

LED light

Magnesium sheet

Carbon sheet

Alligator clip wires

Salt packet

Small cup (for saltwater battery)

Wooden or plastic base

Support rods

Instruction sheet

Age Recommendation

Ages 8+
Reason:

  • Contains small parts
  • Requires wiring and correct handling of magnesium & carbon sheets
  • Involves a simple chemical reaction (saltwater battery)
  • Requires understanding of wind energy and safe generator connection

Difficulty Level

Intermediate
Because the kit involves:

  • Wind turbine assembly
  • Generator + LED wiring
  • Creating a saltwater battery
  • Testing wind speed and blade angle

Safety Notes

Do not ingest salt, magnesium, or carbon materials.

Avoid contact of magnesium sheet with liquids other than saltwater.

Ensure wires are connected only as instructed.

Do not operate the windmill near water sources other than the controlled saltwater cup.

Keep long hair and loose clothing away from spinning blades.

Wash hands after handling magnesium and carbon sheets.

Adult supervision recommended for chemical reaction setup.
