What's a possible way to go through a business card?

Question

For my science class we have to devise a way to go through a business card. Any ideas anyone?

Answer 1

There is an old trick where you take a 3x5 index card, old it length wise.  Make a slit on the folded edge about 1/4 inch from the adjacent edge.  The slit should go almost but not quite all the way to the other side.  Make a second slit next to this one, but start opposite the folded edge.  Continue making slits alternating edges, the final slit should be from the folded edge.  Now you want to cut along the fold from slit to slit (do not cut to edge).   Carefully stretch the card out, you now have a thin "hoop" that you can pass through.
