you can use a few magnets to make this amazing spinning toy. you just need a plastic scale,
a bottle cap, ring magnets and some glue. first take this magnet and put it inside the
bottle cap. stick it with some glue. you have to ensure that the bottle cap is not completely
flat. it should have a circular curvature at the bottom. now take this doll and stick
them so that you have pictures on both the sides. you can see that this doll has a line
of symmetry in the middle and that is where we place an old refill. now the spinning doll
is almost ready. insert a bead at the other end of the refill and stick it inside the
ring magnets. take the other two ring magnets and put them one on top and other at bottom
of the scale so that they are attracted to each other. and you can now start playing
with the doll. tilt your scale a little bit and as soon as you take it towards the doll
it starts rotating and spinning. you have to make sure it is in repelling position.
the curved bottom of the cap makes sure that the repelling force makes the doll rotate.
