Identify the 7 hidden images in these pictures:
Tip: "Cross" your eyes very slowly until you see a 3D image pop out. Then let your eyes relax (but don't uncross them!) until you see the whole image.
If you are having trouble crossing your eyes, hold out your finger in front of a blank wall. Make sure there is a generous amount of space between your finger and the wall. Focus on the wall and not you finger. You should see two images of you finger instead of one.
Once you know the trick to seeing one image, you'll be able to (eventually!) see them all. Good luck!
The answer for "Santa with Christmas Tree" is a bit difficult to get the proper wording. Interestingly, the second, fourth, fifth, and seventh ones were super easy for me to see, and the rest were harder.
