This is the last balloon I made in 2018. Because we were going to watch the ball drop (during the New Year countdown), I thought I’d make something like a ball. Next time I might put a lit round balloon inside. My niece said it’s like a disco ball.

This balloon is a variant of the icosahedron balloon I often make. (I also used it to make the battle mace.) The only difference is that when you twist each unit, you include an extra 3-5″ bubble on each end. Each balloon will be fully used – inflate to almost one inch remaining, and when nearing the end, push the air so that the whole balloon is filled.
