Here we teach you to make a little girl who can dance, when you are tired of studying you can take it out to play and relieve your fatigue.
Materials and Methods
1. Preparation materials: mineral water bottles, enameled wire, large bolts, pieces of cardboard, paper clips, fine thread, scissors, tape, batteries.
2. Cut the mineral water bottle into two parts, take the bottom half with the bottom.
3. Turn the bottom half upside down and cut a 50mm x 50mm square opening on one side, near the bottom, as a "stage".
4. Take 0.5 mm enameled wire in the large bolt around 200 to 300 turns, made of electromagnet.
5. Tape the electromagnet fixed in the bottle above the mouth, and the two wiring through the bottle.
6. Cut a little girl shape out of a piece of cardboard, then use paper clips to make arms and legs.
7. Hang the little girl from the bottom of the "stage mouth" with a thin wire.
At this point, connect and disconnect the power repeatedly, and the little girl will dance with excitement. It's fun!
