Going to infinity and beyond in creating an irritating noise that is capable of destroying ears and brains requires a dress made of balloons like this one. Admittedly though, it is also quite amazing given the balloons stack up nicely to create a Buzz Lightyear costume. Now, as an exercise imagine the sound of that guy walking. Done? You can thank me later.
There’s a video showing the guy move about, and it isn’t that noisy, but that’s also limited mobility. Also, it looks pretty cool so we can easily ignore the implied, imagined or alleged crimes against ears this costume may commit. This and a few other balloon costumes are the work of Jeff and Rachel Wright, who happen to be involved in very worthy acts, apart from the awesome balloon costumes they create.
