p3 Optical illusions--they're fun!

Sometimes our brains process visual information in unusual or unexpected ways, so that what we think we are seeing differs from objective reality.

Study these three examples carefully, then answer the following questions--and remember, things aren't always what they seem!

1. Which center circle is larger?

Answer: They're both the same size!

2. Which diagonal line is longer: AB or BC?

Answer: They're both the same length!

3. Which horizontal bar is bigger, A or B?

Answer: B is much, much bigger! In fact, A is so small it's completely powerless! It might as well just give up! Everyone can see this!
