Wow, what a creative idea! This is not really a craft for small children, but I just wanted to show you what's possible with some drinking straws and a little imagination. Follow the link below, there are lots of cool arts created from straws. Here in Japan, there is a little stop motion animation short program, "Puchi Puchi Anime that has short cartoons and all the characters and backgrounds are made from straws. There are little creatures, shrimp, trees and a dragon. Great food for thought.
