in this very beautiful magnetic toy you spin a fan. you would require an old CD rubber,
pencils, screw, etc. now take an old CD and apply rubber glue across it and then take
a thick piece of rectangular rubber with holes on two ends and stick it on the old CD. then
press fit two new pencils into these holes. apply rubber glue also on the tips of the
pencils and stick two wooden skewers, wooden sticks. now if you take a screw, it will be
attracted to a small magnet. now this magnet in the center of the two sticks. now this
is a propeller made from 7cm diameter card board sheet. you can see these slant lines.
cut all the 8 slant lines and then you will see these black triangles. lift all the black
triangles to make this into a very beautiful propeller. there will be 8 blades. this is
the top view and this is the bottom view. now take an old ball pen and remove its refill.
now take a thin screw minus the head and just screw it in. the pointed end of the screw
will be outside. end of the pen is tapered. you press fit the card fan and place a bicycle
nut for stability. and then hang the screw from the black ferrite magnet and now the
toy is ready. you can see the pen hanging from the magnet. if you place it under a ceiling
fan, air will strike the fans of the card propeller and the whole pen will spin very
fast. so this is essentially a magnetic spinner. here you can see the screw in close up. its
a very very beautiful propeller which can be made with simple materials.
