Challenge your eyes with the classic illusions tricks card, experience the swirling illusions produced by the illusion spinner, view and create 3D pictures.
Over 20 optic fun activities with fun scientific explanations supplied. All packed in a neat carry pouch, it's a cool science kit which guarantees hours of fun.
Make a mirage appear - right before your eyes!
Even the camera sees it. But you can't touch it! And neither will anyone
else.
Scientists call these amazing phenomena three-dimensional
real images. Indeed, the illusions you can create are so brilliant,
so alive with color and depth, they defy, yet demand, explanation.
How quickly can you find out what is unusual about this paragraph? It looks so ordinary that you would think that nothing was wrong with it at all, and in fact, nothing is. But it is unusual. Why? If you study it and think about it you may find out, but I am not going to assist you in any way. You must do it without coaching. No doubt if you work at it for long, it will dawn on you. I don't know. Now, go to work and try your luck.
Answer
The term 'lateral thinking' was coined by Edward de Bono
to denote a problem-solving style that involves looking at the given
situation from unexpected angles.
Sometimes a problem seems difficult or insoluble because our
assumptions about it are wrong.
A classic example:
A father and his son are involved in a car accident,
as a result of which the son is rushed to hospital for emergency
surgery.
The surgeon looks at him and says
"I can't operate on him, he's my son". Explain.
One day a girl celebrated her birthday.
Two days later, her older twin brother celebrated his.
How is this possible?
Answer
A three volume set of books stands on the bookshelf.
Each cover is 1/4 of an inch thick and the pages of each book are 1 inch
thick. A bookworm starts on page 1 of volume 1 and eats his way to the
last page of volume 3. How far does he travel?
Answer
Some two-dimensional figures can be interpreted as solid objects in
more than one way. A well-known example of this is the flat
representation of a wire-frame cube, which can be seen as if from
above, or below.
Impossible objects typically look at first as if they could exist
in reality, but on closer inspection, you find some aspect that just
cannot make sense...
Artists have designed impossible objects, like the classic impossible
triangle. M.C. Escher, created impossible objects, illusions, and
tessellations. Swedish artist, Oscar Reutersvard, known as the father
of impossible figures, was the first to purposely structure impossible
objects.
Optical Illusions take on an extra dimension when they are animated.
Sometimes the animation reveals the deception, perhaps by removing
the elements that cause it, or by bringing in elements that allow a
truer comparison. Sometimes the animation sharpens the illusion.
See for yourself!
Moir� fringes are an interference pattern that is formed when two similar grid-like patterns are superimposed.
Ambiguous figures are 'two pictures in one' - looked at one way, you
see one thing (e.g. a vase), but looked at another, you see something
else (e.g. two faces in profile).
They are somewhat similar to unstable figures, in that there are two
ways to interpret each one, but unstable figures don't contain
different subjects; they contain one subject that flips perspective.
