The trumplet is made out of a a cone, a pvc pipe with 3 holes in it, and a tube connector. You blow into it like a trumpet and plug the 3 holes to make different sounds. We were going to make something else but then we stuck the cone onto the connector and blew into it and it made an awesome sound, so we drilled 3 holes into a pvc pipe and out it in between. So thats our instrument!
