Fun stuff to do
Optical Illusions
Your eyes can play tricks on you. Pictures that confuse your eyes and brain, tricking them into seeing something differently, are called optical illusions. See if you can figure out these optical illusions.
WHICH OBJECT IS TALLER? (None: They’re all the same size.)
WHICH LINE IS LONGER? (Neither: They’re both the same.)
IS THIS GRAY HAZE SHRINKING?
(Stare at the black dot. After a while the gray haze will appear to shrink.)
DO THESE COLORED LINES BEND?
(No, they’re perfectly straight—but try telling your eyes that!)
ARE THESE WHEELS SPINNING?
(Stare at the center. Now move your head back and forth toward and away from the page. The circles will appear to spin.)
HOW MANY BLACK DOTS CAN YOU COUNT? (Look closely and you will see them.)
DO YOU SEE TWO FACES OR A VASE?
(If you see one, close your eyes for a moment, then look for the other.)
ARE THESE LINES STRAIGHT OR CROOKED?
(Yep, you guessed it. The horizontal lines look crooked, but they are perfectly straight.)
ARE YOU SEEING RED, WHITE & BLUE? (Stare at the center of this flag for one minute. Then look at an empty white sheet and you’ll see a red, white and blue flag.)
HOW THIS FLAG WORKS
Your eyes see color as measures of red or green, blue or yellow and bright or dark. When you look at a green object for a long time, your eyes get tired and start seeing red. When you look at yellow, after a while you’ll start to see blue. And darkness turns into brightness. The result: Even this wacky flag can be good, old red, white and blue—after a while!

This was really cool!! I have a book on optical illusions which has a lot of the same pictures as this activity page. The only thing that didn’t work for me was the “which person is taller” thing. I’ve doe something like that in art class, so kind of saw right through that one. The other ones were awesome, and I really liked the flag. Be sure to stare at it for a full minute, because I tried to cut the tme and it didn’t work! The “Is This Gray Haze Shrinking?” trick is really interesting, because the haze almost disapers. For the “How Many Black Dots Do You See?” one, the dots are white, but apper to jump around, because you are staring at a black grid, so you see a few black dots in different places, but then they are gone!
There is another optical illusions trick I know too, the color one. Is is where you look at about 10 words and each word says a color and is a color. For example the word “pink” would be the color red. The word “green” would be the color black. You are supposed to say the word, not the color of the word. (Confusing, huh?) It is a lot harder then it sounds and you get really mixed up! Thanks for the illusions!

The flag was amazing. All I had to to was blink at the paper, and every time I blinked, I saw the flag.

these are all actually quite simple to figure out if you just think, or if youve seen them already lol.
