The amateur shows how to make a pentakis dodecahedron of balloons. This balloon has 90 bubbles and is made out of six balloons. Its a good balloon exercise to do to challenge your balloon making skills. On the shape there are either six or five balloons meeting in one space. It is a shape of a sub divide pentagon. On the top is a vertex and coming off the top is a face. This is the kind of balloon you should make to practice your 3-d skill making.
