Balloons too, can be used to make complex geometrical shapes if aligned properly and made skillfully. For this video however, you would only need standard cylindrical shaped balloons. The first step requires a partially filled cylindrical balloon. Next, the balloon is twisted and divided into 20 separate balloons which are then again twisted to form an "eight shape". The unfilled part of the balloon acts as a buffer zone when the balloon is twisted and separated. The above process is then repeated 5 more times in the video to create five more "eight shapes". These are then joined by using the flexible joints of the balloons and shaped to form a dodecahedron.
