Now you blow into the end you just cut. It may take a bit of practice to figure out where best to put your lips and teeth, but eventually you'll get a sorta duck call sound. This is harder for kids because their lungs aren't as big and they can't blow out as much air, but my 5 year old was eventually able to get it to work. After this we experimented a bit by attaching straws to each other. We ended up making several different sounds. I'd play the videos for you, but the sounds are very annoying on the video. You'll just have to try it out for yourself!
