How to Create an optical illusion with a safety pin
This video is about an optical illusion of a straw going through a safety pin. It is a simple illusion that any one can do. First, you need a safety pin, a toothpick and a straw. Cut the straw to the size of the toothpick, and using the safety pin, pierce straw and the toothpick from the middle. Then close the pin. Then all you've got to do is to hold the straw to the safety pin and release it. The straw will rotate almost 180 degrees creating the illusion of going through the safety pin to the other side.
