Solving "Spot the difference" Puzzle

Remember those ‘Spot the difference pictures’ puzzle games when you were a kid? Remember how long it took you to find them all? I had troubles - enough so that I was the last person to finish them and go out and play kickball! No longer, I say!

Introducing a sure-fire way to find all the differences in “spot the difference” picture puzzles in a matter of seconds. Only two requirements:

* You must have that “magic eye” skill used with those goofy pictures from the 90’s (involving crossing your eyes)
* The “spot the difference” pictures should be side by side for this technique to work. If they are below and above each other, just rotate the pictures/page so they are side by side. If they are skewed, you can tilt your head a bit…although you’d probably look a little funny.

Ok, once you have found a suitable picture…

1. Stare at the pictures, begin to cross your eyes.
2. You should see a third image appear between the two pictures.
3. Focus on the middle picture, adjusting the tilt of your head so both pictures line up exactly.
4. Once you’ve focused on the image, all the differences should look “luminescent”.
