How to use - Lighthouse

  • Move the white (smaller) bottle in the green (larger) bottle full of water.


    Air will be expelled from the cap's hole on the green bottle and will rotate the turbine.


    This movement will be transformed into electricity by the generator (magnet + copper wire) and the LED will light up like a real light house.

  • This video shows the lighthouse in action !
