How well do you trust your mind? We can’t even imagine how often our sight, hearing, or smell cheat us.
Bright Side will show you 18 puzzles, optical illusions, and tricks, which can prove that things are not as simple as they seem. You will also see an incredible bonus, which will make you check twice before understanding what you actually see.
Look at the left picture for 30 seconds, and then move your sight to the right picture. You’ll see the dinosaur becoming green. The effect is active until you blink.
The Ambassadors is a painting by Hans Holbein the Younger. You can see an obscure stain on the floor between the 2 men. If you take a close look from the right, you’ll see a tridimensional skull.
This illusion is created because of the contrast between the vertical lines. With the animated video stopped, it is possible to see this. The illusion where the animated pigeon is moving its neck was named the best optical illusion in 2014.
Take 2 cartons of milk. Put one of them in the freezer for an hour, while the second carton is in the kitchen, acquiring room temperature. Then take both cartons into your hands in an hour. Frozen milk will seem heavier than warm milk. This effect is known as Weber’s Phenomenon.
Our brain always sees strawberries in a red color. That is why it automatically "sees" the berries in this pic in the same way. However, there are only gray, blue, and green shades here. You can find a more detailed explanation here.
Do you think this picture was taken from the inside of the building or from the outside? You’ll find the answer in Budapest: if you are somewhere near, don’t forget to visit the Paris Courtyard.
If you take a fleeting glance at the picture, you might think that all the spots are different in size. The illusion is produced because of the different backlashes between them. All the spots actually have the same size.
You might cut out all the figures at home to see the reality of this illusion. But why is it so? Take a look at the angles of all the triangles. They are slightly different in angle degrees. It is exactly this difference that makes a square in sum.
You can repeat the action thrice and divide the sum of your time into 3. Most people will have the same result as in the table. The secret is quite simple: our sense of balance gets worse as we get older. However, the numbers can change if you play certain sports that require balance training.
Our brain likes to see round things. That is why, even when having only a detail of something round in sight, you automatically draw the full round object in your mind. The same thing occurs when you look at the Google logo, which is absolutely not as round as it seems at first.
This is Melbourne, Australia. The building is unique because it represents an interesting geometric illusion found on the wall of a café in Bristol in 1973 (though some people say the illusion was found earlier). All the straight black-and-white lines and objects are parallel to each other, but your brain refuses to understand it.
Does it work? If yes, you still have a chance of becoming a good drummer or juggler. Most people just can’t make different actions with different hands at the same time unless they are trained to do it.
However, your brain sees only the 3D illusion created by a group of artists. The effect is stronger because of the reflections you see in the glass doors.
This effect is unbelievable. But if the line in the middle was removed, you’d see an absolutely symmetrical arch.
Your brain works perfectly with different kinds of perspective. It will surely show you that the most distant and the closest lines have different lengths. However, if all the squares are removed, you’ll see that the lines are identical.
This is one of the most famous optical geometric illusions. Actually, there is no right answer. It might be that the cube lacks one corner, the cube is inside the cube, or the cube is in front of the cube. If you like origami, you can make such a thing yourself.
Don’t believe us? If you want to see them, you need to concentrate your attention on the vertical lines. Now the circles are seen more distinctively.
Most people will not be able to distinguish between boiled eggs and marshmallows. This occurs because your brain usually knows the taste of products by their odor. If there is no odor, there is no taste. The trick is used by smart kids when they are made to eat "healthy food" they don’t want or like.
One of the most interesting kinds of optical illusions is body art. Artists create hyper-realistic pictures on people’s bodies and faces, and it’s not so easy to see them under the layer of paint. It’s like a pic inside a pic.
Let us also say a couple of words about various pics that are changed with the help of photodesign applications and programs. Surely these are not optical illusions as such, but you can also be puzzled by what they illustrate. After all, the main aim here is to test your brain while understanding what your eyes see.
Optical illusions and various riddles perfectly test your brain! Which of the illusions shown here did you like more? Don’t be shy to share below!
