So this is a just crazy giant aluminum box filled with helium. It was designed by artist, JunyaIshigami, and is apparently a part of a project called “space for your future”. He was able to make what I can only assume is the world’s first square balloon. When I was little, I tried to get my sister to float by filling her with helium. I was unsuccessful, but her voice sounded like she missed puberty until she was 20. Now she sounds like a man. A big, baritone man. She regularly sends me hate mail.
Another video (all in Japanese) about it after the jump.
