Tight fit
Cut a hole in the center of an index card just large enough for a small coin to pass through. How can you push a large coin through the hole without tearing the index card?
Heh, there are two ways to do this. One is to place the coin on the table, and put your finger through the hole and push the coin through the hole.
Or, place the coin on the hole. Fold the card in half so you essentially have an envelope. Lift it up so the paper is perpendicular to the table and a bit of the coin is sticking out of the semi-circular hole. Lift up from the bottom edges, and the coin can fall through.
Admittedly, with the second one, the hole can't be TOO small, but you should be able to fit a half-dollar through a quarter hole.

I have done this before. I folded the card in half.
ReplyDeletedsoldier, you have it right on both angles.
