Thaumatrope
A Thaumatrope is a device (toy) that creates and
optical illusion it blends two images together that make us see something move
this is caused by our persistence of vision.
The Device (Toy) was popular in the 19th
century created around in London by Sir John Herschel but John Ayrton Paris and
Peter Mark Roget Popularized it to demonstrate the device.
In 1824 John Ayrton Paris used the device to
Demonstrate persistence of view to the Royal College of Physicians around 1824 The
Device Works By having two separate images on a piece of paper or cardboard for
example a fish one side a bowl on the other with two pieces of elastic or
string tied to both sides witch are twirled to make the piece of paper or
cardboard spin witch creates the optical illusion alternatively you could stick
the piece of paper or cardboard on a stick and use the pam of your hand to spin
it.
The advantages of using our persistence of vision
is best described by watching movies or television our vision lets us enjoy the
images that flash in rapid succession to create the illusion even though to our
eyes is seems like a constant lit screen it also stops us from seeing the world
as black every time we blink for a split second.
This is how you make a thaumatrope
