When I have a concept for the project weight, I did some experiments for balloon.For balloon part, I hope that it seems black balloon popped by themselves one by one. I think I can use some softwares to deal with this effect. Such as photoshop and premiere. Eventually, Jonathan told me that I can put some needles with plasticine on the floor, which is a very useful idea. I prepared almost 100 balloons for each experiment. Due to the cause of sound, light and tool, I did three times experiments respectively.
These pictures are taken by the process of experiments.
