Phenakistoscopes area unit terribly simple to construct. they'll be an excellent thanks to introduce youngsters to crafts - they'll find it irresistible once it eventually plays the 'video' of the photographs they stuck on that - or perhaps a fun recreation for adults.
Phenakistoscope illustration
Here's a way to produce this straightforward and fun animation device.WARNING: youngsters ought to be supervised whereas exploitation sharp objects like scissors and pins
What you will need

► Thick cardboard
► Scissors
► Compass (geometrical) and pencil
► Glue
► Marker pen / coloured pencil

Instructions
1. Draw a circle on a thick cardboard employing a compass.
2. Cut out the phenakistoscope wheel. this can be your viewing wheel.

4. realize printable copies of the look, or sketch them yourself if you'll.
5. Paste the look on the cardboard wheel. instead, paste the look on a paper circle and so paste the paper wheel on the cardboard wheel.
6. Cut vertical slits from the sting or from the middle of the wheel (as shown within the high right image). beware to not withdraw the look.
