When your teacher brings in an optical illusion to show the class, you just know it was going to be a good day! Every so often, while on Facebook, Twitter, etc., someone posts an optical illusion! Here's the best of this week!
1.
2.
An oldie but goodie! How many legs does the elephant have?
3.
Is it a women's face or a word (that might even describe her).
4.
Is it a rabbit? Or a duck? The earliest drawn version of this illusion can be traced back to 1892!
