Easy funny Kids horn - Trumpet

cults3d

The task was to design a simple trumpet for my 3-year-old. It works with a thin elastic material (plastic bag, cling film, silicone cover for cans (see picture), or a piece of rubber glove) held in place by the ring. Then you blow through the hole in the side and you get a sound, if not, you have to make sure that the membrane is straight and tense. My children love this horn and we don't find the sound too disturbing :-D. Sounds a bit like the "horn of Gondor" (the sound depends on the diaphragm material and its thickness).
