black marker (or black crayon)
3-5 crayons or colored pencils that go well together
Start by drawing a “hilly” line across your paper with the black crayon. Then place dots on the line at various intervals. The overall finished effect is best when some dots are closer together and others farther apart from each other.
Starting at the edge of the paper above the line, connect the dots going across making ‘bumps’ or ‘frowny mouths’ between the dots. Do not cross the line!
Do the same below the line only make ‘smiley mouths’ or ‘u’s to connect the dots. Don’t you like our technical terms?
Keep adding more lines until the paper is filled. Do not ever cross any lines. Obviously you won’t be able to connect the dots every time. Just follow the same pattern or series of bumps or U’s varying the spacing between the lines.
Tada! A really cool looking 3D illusion! Now how about creating a 3D hand?
First place your hand on the paper at an angle, then trace lightly with a pencil. (This photo is blurry as the camera couldn’t pick up the light pencil line so it wouldn’t focus!) If you look close there is a hand on there!
With a black crayon or marker (fine point markers work best) freehand draw straight lines across the paper, except when you get to a pencil line “bump” the line until the next pencil line and then continue going straight.
The closer the lines are the better the illusion. See more 3D hand illusions here.
I’ve also found this is a good “keep the kids quiet during church” activity. :)
