Psychics porn is the only way I can get off anymore.
First, I stopped being attracted to Real Life women. Then cartoon women stopped doing it. Then cartoon bears made my boner all soft. But goddamn iffin I didn't shoot a load to this.
The cornstarch/water slurry is rheopectic, which means that as pressure is applied its viscosity increases. The subwoofer applies a little bit of pressure all over the place, and when pressure is applied faster than the slurry can return to standard viscosity you start to get the "buildup" effects. Tons of little variants in the system (such as differences in thickness of the slurry at any given point) cause the little writhing towers to rise from the muck.
