How to make a optical illusion
Start with a piece of paper!
Draw a squiggle like the one in the picture, in the middle of the page!
Make a half circle like this on each side of the line. Continue along the whole line...
Start adding half circles one at a time across the whole line until you finish it...
Now do the other side the same way and it should turn out somewhat like this!
Here are some others I have done! They will all turn out differently! You can make some lines bigger than others so some look they disappear!
