Thaumatrope
- Invented in the 1820s
- Name means “magic turn”
- Designed to amuse children
- Made of 2 pieces of paper and string
- One image on the front, another on the
back. As it spins it gives the illusion of combining the images.
How
Does a Thaumatrope
Work?
•When the strings are twirled quickly
between the fingers the two pictures appear to combine into a single image due
to persistence
of vision
•Persistence of vision -
the eye's ability to retain an image for roughly 1/20 of a second after the
object is gone.
•The eye continues to see the two images
on either side of the thaumatrope
shortly after each has disappeared. As the thaumatrope spins, the series of quick flashes is
interpreted as one continuous image.
