Black
and white disks are illustrated with graphics
that are affected by the strobe in fascinating
ways. You can interchange the disks on the
fan and adjust the frequency of the strobe
flash to see moving images or optical illusions.
Go ahead and try your own pattern. Take a
paper plate, draw a pattern on it, then place
the finished pattern on the fan wheel.

What's
Happening Here?
How light affects how we see things,
how frequency of the strobe flash can
create different images, and how children
can create their own visual patterns.
Discovery Questions:
What happens when you change patterns?
What effect does the flickering of the
strobe light have on things as they
speed up? Is it better to use dark colors
or light colors for your own pattern?
