A simple way to build an electromagnetic generator!
Supplies
Materials: cardboard, bottle cap, straw, propeller, motor, led light, glue
Tools: pencil, ruler, scissors, xacto knife, glue gun
Draw Sides for the "windmill" on Cardboard

Make them all even, with smaller tops than bottoms. Use a ruler to help. Create and add your own cut outs!
Cut Out Pieces

The xacto knife is helpful for the cut outs. Save a piece for the base!
Create the Windmill Stand

Glue each piece to the base and to each other (I used hot glue). Make sure they are touching on all sides!
Glue on the Top

Find a piece from the scraps that will fit on top of the stand. Shape it into a square and glue it on.
Glue on Base for Light Stand

Any type of small plastic bottle cap will do.
Gather Pieces for Light Stand

Look trough the scras from the cut outs. Create 4 identical pieces, along with one square piece.
Glue Together the Stand

Using the glue gun, glue the short side of the pieces to the square. Make sure the sides of the pieces touch.
Glue Light Stand On

Glue the light stand onto the top of the bottle cap, alonging room for the edge to hang over.
Insert LED Light

Create a small hole in the center of the square backing. Insert the light into the whole, with the metal sticking out the back.
Glue Straw Onto Motor

Cut a small piece of the straw off. Glue it to the axle of the motor, with extra hanging off.
Add the Propellor

Glue the propellor to the opposite end of the straw.
Glue the Motor on
![IMG-3570.jpg](/proxy/?url=https://content.instructables.com/FQT/ES6F/KOYC1EP0/FQTES6FKOYC1EP0.jpg&filename=IMG-3570.jpg)
Glue the large part of the motor to the cardboard, with the fan towards the front.
Connect the Wires

Create a hook with the metal extending out of the wire. DO the same with the LED. Make hook each write a different leg of the LED. Make sure the legs do not touch.
