While preparing some things for this year's Burningman festival , I stumbled upon this amazing page of bullshit science toys which I, would I have the money, without exception all buy immediately.

What brought me there? I was Googling for "Disgustoscope Burningman" to see if anyone has thought about this before. I will probably do this... a cheap installation I could bring. Of course, a disgustoscope only shows what you bring in, so it would be ideal for Burningman.
