A Big Hole
How can you cut a hole in a 5"x8" index card large enough for a person to walk through?
AnswerFold the index card in half lengthwise. Start cutting from the folded side near one of the edges. Do not cut all the way through, but rather, stop about 5mm from the edge. Do this on both sides. Now alternate your cutting so you start from the open side, then from the folded side (zig zag formation). Keep your cuts no more than 5mm apart. When you have finished cutting the whole index card in this fashion, cut open the folded side leaving the two end folded sides intact. Open your creation into a large hole big enough for someone to walk through.
