A long time ago in Japan, people discovered something amazing: you can fold paper, make just one straight cut, and end up with almost any shape you want! Even stars, hearts, and letters can appear like magic, and magicians such as Harry Houdini loved showing this trick. Later, some very clever mathematicians proved that this “Fold and Cut Theorem” really works every time. It feels like a magic trick, but it’s actually math in disguise. Now grab some paper, fold, snip, and see what surprising shapes you can create!
