What you need:
- A colour print out of the colour wheel above
- Glue
- Cardboard
- Scissors
- Pencil
How you do it:
Print out the colour wheel above.
Glue the colour wheel to a sheet of
cardboard. Wait for the glue to dry.
Once the glue is dry, pierce the the
middle of the colour wheel with scissors (ask a parent or guardian
for help here).
Insert a pencil through the hole until the colour wheel is about
a third of the way along the pencil.
Spin the disc and watch what
happens...
