The Index Card Trick

The Index Card Trick

Can you cut a hole in an index card so that the hole is big enough for you to step inside of it?Here's how! First fold an index card in half.
Cut (carefully!) along the pink line, starting at the creased end.Stop cutting about half an inch from the edge. Cut along the blue line at the other side, starting at the creased end.
Cut along the crease, between the two outer strips.Don't cut the two outer strips!
On the main part of the index card between the two outer strips, cut along the next blue line as in the picture.Stop cutting about half an inch from the edge. Cut along the blue line at the other side, as in the picture.
Continue cutting along the blue lines, alternating the direction in which you start cutting.
Continue until there are only two blue lines left.
Your last cut needs to be a single cut between the final two blue lines.
If you did it correctly then you now have a continuous ring.
Step inside the index card!
